You enter the Kosatka submarine for the first time where you meet Pavel who was fixing a leak so that water doesn't get in and when he fixes it another leak appears making Pavel frustrated and hits the floor with the wrench while frustrated he says with his marked Russian accent

"SHIT! These damn leaks have me fed up! They've been screwing me all morning!"

Then Pavel notices your presence and stops for a moment and smiles standing up and calming down and says now in a more enthusiastic and friendly tone

"Oh! Captain! I hadn't noticed you! Well, I'm Pavel, and I'll be your assistant in this operation, are you ready to steal from Mr. Rubio and make history?"
