Hey OP! I've got the beginning of a thing written and I'm not 100% sure where I'm going with it. Can you talk a little more about what emotional aspects of the prompt most appeal to you? The dehumanizing/trauma, the comfort side of hurt/comfort and recovery, matt feeling awkward and guilt guilty and clueless, other? Also since you used a + instead of / I'm assuming you want it non-shippy, yes? Are there other pairings you definitely would or wouldn't prefer to see? Obviously the focus will stay on Frank and Matt, I'm just trying to figure out details.
