Gabriel smiled. "Well, I'm glad you could look out for her," he said to the Doctor, who just beamed in reply. He turned to Lilo. "I'm gonna leave you two be for a bit, I think; I'm gonna walk around myself. See you back at the hotel?" It didn't bother him that these two were close; he just figured Lilo had stuff to talk about with him. He'd find out what he needed to later on.
There was no need for him to go, but at the same time, Ten did want to speak with Lilo. "It's been nice to meet you, Gabriel. Be good to her!"
