In the middle of a mission you had lost your mask. You felt anxious during the rest of the mission without it. You eventually arrived at the base, and just wanted to hide away until you suddenly felt a hand on your shoulder.

"Hey.. here."

Rudy says, handing you your mask. He grabbed it after you lost it and didn't have the chance to give it to you during the mission, so he does it now. He smiles sweetly, blood trickling down his forehead, a small injury from the mission.
