I personally had the thought that erynn was there as all this was happening and would have gone in, but i dont think the mc is a pussy, i said last update that he reacts good for the most part. i think this is more of a move to push the story in a certain way than the mc being wrote as a pussy. thats just my opinion.
I think if the story was wrote how he is so far he would have went in and got erynn, phoned erynn at least and made sure she is good, but its like in horror films when a character does something stupid, its needed for the story to get to the next point.
