I hate feeling like this

Sam flung the door open to the study with more strength then everyone else thought he had, his face filled with so much worry, it was almost as if his child had gotten injured, not his Master. 

"My Lord!" Sam shouted, taking in the way Cass was slumped against Draken's chest, his eyes fluttering, his breathing light, and he let out a noise that sounded like between a screech and a wail, moving towards Cass at a speed the others were surprised at. 

Sam cupped Cass' face tenderly, his other hand going to his throat, checking his pulse. 

"Oh no. Oh no oh no. What was in what the Doctor gave us? I thought it was going to be okay! I checked it! Oh no." Sam was muttering to himself, worried to all hell, while Draken rumbled. 

"Did you not watch them make it?" Draken demanded and Sam's gaze slid up to meet the dragon's. Sam nodded.
