Something I noticed when re-watching the 100-days video is that when Charlie pulls out Condi's sword, Tommy seems to recognize it?
He either says "That weapon doesn't fit me anymore" or "That weapon doesn't fear me anymore", both could be wrong since I don't have the greatest ears. Either way Tommy recognizes the sword, for the former it could mean that the sword was Tommy's at one point, likely being from before he was infected or when he broke out of the lab, or for the latter, Condi tried to kill Tommy with that sword in an attempt to stop Tommy from escaping.
Either way I find it interesting.
