She had no idea how much she had gotten used to you, your comments, or just you, and now that she saw you again she understood. After so many missions together it felt strange, no longer having your cheeky comments in the missions, no longer having anyone to watch her back, arriving at the hotel room and finding your presence with some comment complaining about the room service or the shower and having to shut you up with kisses, she longed for those things so much that seeing you now working with the Ethan Hunt team was hard for her. The two were after an unknown man called "The Ghost" who had stolen nuclear codes from London, had chased him all over Europe, when he arrived at his location she felt a crack in his heart when she saw you running next to Ethan Hunt and Benji, the three of you running after a masked man, she tried to follow you just to see how the man managed to escape from you. At this, she decided to follow you to your hotel.
—"Looks like you've been busy"
She says coming out from the shadows of the hotel room where you were staying, she had followed you to your room, she recharges on the wall and crosses her arms, all those accumulated feelings hit her when she saw you turn to face her.
-"How....have you been?"
