A *really* great start. I love all of the background details you guys are filling in as we move forward. Things like reference to bits of common history, or feelings about other characters. It adds a lot of depth and I'm used to groups where I have to push and pull to get some of that out of them. You're all just doing it off the cuff!
As a reminder, there is no door - there is a rubble pile in front of the broken door such that you will have to scramble up the pile and squeeze through, one at a time, a narrow opening.
