Diarmuid doesn't need to be told again. He nods to Bucky and then pulls his cloak hood back over his head so he's invisible again. After taking a moment to listen at the door and make sure no one is out there, he opens it again and slips out. His footsteps are silent as he makes it way to the door. Part of him expects there to be something he needs to unlock when he gets to the door, but after looking things over, he finds nothing.

"I guess it just opens," Diarmuid's words are barely a whisper as he reaches up to push the door open. He then braces, ready to run if some kind of alarm goes off. Hopefully, though, nothing will happen besides the group finally being reunited when Steve joins them...
