Shut Up, Hawkeye
Ah, the first Frank/Trapper story... ever. Yeah, it all started here. With me. The unlikeliest source.

Here's the gist, Hawkeye finds Trap and Frank sleeping in the same cot and goes catatonic. The night before is played out through the situations of different characters. The whole shazaam will culminate into Frank and Trapper waking up and facing the music... as soon as I write that.
