As Issac entered the shadowy hall he continued to regret his decision to come here,ignoring this he greeted Cara with a simple "hey" at that he continued into the main room.
 Upon entering the main room Issac noticed the lame party,and the awkward mood.Thinking to himself"i thought she invited a lot of people! ahhh this gonna be weird..." sighing 
quietly he walked into the room not even remotely sure of what he could do that wouldn't be awkward,or weird given the awkward circumstances.
