"I like her already." Senna commented as she heard Z snicker as Ace's reaction. "At least she has a sense of humor when it comes to my jokes." She said loudly, giving Tim a look. Tim made a face at Senna. "Maybe because, at least so far, she hasn't been a victim of one." he replied cooly. Senna rolled her eyes. "You just have a stick up your ass." 

"So, uh, welcome to Gotham." Tim said to the unknown girl. "My name is Tim Drake. This crazy lady is Senna Sacker." He held out his hand politely for a handshake. "Where are you from?" Not that Senna didn't already know. Tim only went snooping when he had the interest, and he wasn't a creeper like Senna could be.
