Julian is laser-focused on his task and so he nearly misses it when Garak starts talking. He only briefly looks up, realizing how terrible Garak looks. He's lost quite a bit of blood already. He pulls a sealed water bottle out of his backpack as well, holding it out to the other.

"Drink." It's not that he hasn't heard the other. He heard everything loud and clear. It just simply won't dissuade him from continuing his work. Julian finishes disinfecting the wounds as best he can and starts to firmly wrap one of Garak's legs, first with gauze, then with a pressure bandage to keep from oozing too much.
