Trenton grinned- "You should have petted Fluffy when you had the chance, he was so, well, Fluffy, it was great."
Hermione gave a poor smile- "I'll have to take your word for it." only to flinch moments later when a disgruntled Rocky brushed up against her after feeling betrayed by Trenton. Rocky sensing her unease felt further sad as his tail completely dropped, whining at how no one loves him anymore.
Trenton watched in amazement as Rocky visibly shrank back to when he was a puppy. Amazed he picked up the cute little thing and chuckled- "Wow, what other surprises do you hold I wonder? Don't get me wrong though, I'll love you no matter what." he said as he rubbed his face into the tiny pup, enjoying the soft feeling against his cheek.
Trenton then looked at Hermione who was also very surprised at all the things Rocky could do, but he could see the distant cautious look coming from her towards Rocky.
Trenton frowned- "Hermione you can't honestly be scared of Rocky, can you? He was protecting you."
He then lifts the adorable pup in front of her who was whining sadly at her before sticking out his tongue to lick her nose which made Hermione break out in laughter as she grabs Rocky and hugs him, apologizing- "I'm sorry Rocky, I could never be scared of you, I just experienced too much all at once is all, thank you for protecting me." she said giving him a kiss.
Trenton never thought he would be jealous of a dog one day as he gave Rocky a glare from behind who looked around in confusion from where the hostility was coming from never expecting it to be from his master before shrugging it off as Hermione started giving him belly rubs.
Breaking it up he bid her goodnight- "I'm sorry you had to experience something scary, I hope you dream of something nice instead, good night Hermione and sweet dreams."
Hermione gave him a good night hug- "You don't have to apologize it wasn't your fault, Good night Trent and thanks for being there for me once again."
Trenton could only wryly smile, feeling even guiltier for putting her through that. He tried to comfort himself with the knowledge that she's been through this before and she would be alright, but it didn't help. The last thing he wanted to do was hurt her in any way, otherwise what was the point in coming back if she was only going to experience the same pain again.
________________________________________
The next day they got together again with their friends but kept what Rocky could do to themselves with Trenton telling him not to show anyone unless it was absolutely necessary so it could be their hidden ace, but during the night he was wondering if it was worth it as Rocky slept in his regular adult dog form taking up more then half the bed again as he snuggled up against Trenton.
Trenton tried talking to Hermione about making Ravenclaw friends when she mentioned how she wished they weren't all in Hufflepuff. She was still having difficulty breaking in with them because they usually just all start reading, so Trenton reminded her of how they became friends with reading and told her to try similar things which she promised to do.
He then spent some time alone with Rocky, venturing around the far side of the lake, playing fetch with a stick he found.
Rocky was very interested in the water as he ran along its banks, splashing around. Seeing how much he was enjoying it, Trenton decided to throw the stick out into the water to get him swimming which Rocky was still a bit hesitant to try.
Rocky ran out chest-deep before stopping and barking frustratingly as he clawed out giving a splash wishing he could just somehow pull the stick back towards him without going out into the unknown.
Trenton grinned as he encouraged him to go on and give it a try- "You can do it, come on Rocky, swim boy, swim, it's just right there." he said pointing at the stick that was just far enough away that he had to swim a tiny distance to get it.
Rocky hearing the encouragement took the leap of faith as he strode forward in an attempt to get the stick and started to swim for the first time, though a bit rough at first as he had to cough up some water that he accidentally breathed in when swimming back with the stick in his mouth.
Theoric petted the excited pooch as he returned the stick to his feet, avoiding the dog shake to get rid of the excess water,- "Haha, that was fun now wasn't it, see you can swim just fine, how about we try it again." he said throwing the stick back out onto the lake for Rocky to chase.
After the 4th throw into the lake, all that splashing brought unwanted attention as Rocky who was happily swimming with the stick in his mouth was suddenly, violently pulled underwater.
Trenton's eyes went wide as he ran to the edge of the water frantically calling out- "Rocky! Rocky!"
He was aware of the denizens of the lake, but he wasn't worried about any of them harming Rocky after learning about his ability, but that didn't stop him from freaking out all the same when he saw his loving dog pulled under.
He should have known that while students were protected from attacks by the lake creatures, the same couldn't be said for familiars who the teachers would likely take as a lesson for the student if they happened to lose them in such a way.
Wading into the water Theoric started to grow more worried as the seconds passe. Fear was soon replaced by anger as he clenched his fist with tiny red sparks of magic trailing around the outside unbeknownst to him.
Suddenly the water erupted as a giant Rocky burst forth flinging a couple of creatures off of him with one nasty little Grindylow still chewing on his hind leg. Uninjured thanks to his magically tough fur and skin., he angrily turned around and chomped up the little bugger as he angrily chewed it to death, swallowing it whole with the other two fleeing in fear upon seeing the drastic change in their prey.
Releasing his fists Trenton happily called out- "Rocky! You silly dog, why didn't you do that sooner, making me worry for nothing."
Rocky hearing his master call looked over and ran towards him, shrinking as he went, before barrelling into Trenton's waiting arms, seeking comfort while giving sad complaining whines about getting attacked, now feeling safe next to his master.
"Hopefully eating that thing doesn't make you sick, especially after you shrunk back down, magic sure is mysterious at times."
Happy that everything went okay, both of them now soaked decided that was enough for today as they headed back to Hogwarts. He was glad no one was around to see what happened otherwise he may have never heard the end of it. Only crazy people like Hagrid had something as dangerous as a Cerberus, he was just lucky to find the only survivor of an experiment that worked and gave him such an amazing dog.
