The Chronicles of Mercenaries, Pitch Black
"Tony?" Kitty walked into the living room where all of the Avengers were relaxing. "Can I talk to you for a minute?"
Tony and Clint stopped their conversation to look up at Kitty. "Yeah, of course."
Kitty led him up to her room to talk and Tony was surprised to see the entire floor gutted out of all of her belongings. "Where's all your stuff?"
"It's in a storage locker." She paused, her eyes cast down at the floor. "Tony, I'm gonna go."
"What do you mean you're going to go?" Tony's eyebrows knit together and he shook his head. "Kitty-"
"I think we both know I need to do this. You guys need Bruce Banner more than you need me and if me leaving is what brings him back," Kitty sighed and picked up her backpack. She slung it over her shoulder. "Then it's worth it."
"Kit, you leaving won't bring him back." Tony said gently.
"Tony, I love you. All of you guys." Kitty hugged him. "But my flights in an hour."
