Around the time Abi reached Tony's house she'd be getting a call. When Peter said "Tony's Place" he meant the flying ship they'd used so much. Tristan was sure Abi knew that. But when he led Vance and Chelsea there and saw that Abi wasn't on board he called her. "Um... Abi? You... You do know we were going to the ship right? You know... Where we trained... More secure than even the Helicarrier?" He asked her trying not to embarrass her. 

(Heh... I couldn't help it XD)
