We Survived.

Alex was surprised at how strong his opponent has gotten in this little amount of time. The injuries he inflicts on Alex were refusing to heal, it was like something was preventing it from healing, and also vice versa. 

"I can feel your life is greatly diminishing, whatever you did to boost your strength to this extent is killing you." Andrew only growls as a response

"You have completely turned into a beast, you can't hold a normal conversation. Lucky you, I am somewhat of a beast myself." Alex dashed towards him and they continued their fighting. Though Andrew couldn't think he still has his ability to think and he is only thinking about how they have puked the hornets' nest. When he took the serum he was sure that Alex's death it's certain but after he engaged him in fighting, he noticed the limitless possibility Alex holds. When the weather started to change, Andrew thought it was his doing but only later did he realize that it was Alex's doing.
