It's Bruce/Clint and I remember it featured Kurt Wagner.
In the beginning, Clint is looking for Bruce and he asks a barkeeper where he can find a monster. He ends up finding Kurt and helping him escape from some baddies. The part I remember most is that Clint finds Bruce and he's standing in front of some windows and gets shot a few times. Kurt shows up and transports Clint and Bruce to safety and I'm pretty sure that Bruce shares some of his blood to save Clint.
Can anyone hlep???
