"If you were human, I'm sure you'd like to be with me." He said as he flew towards the warehouse where there is a minefield of criminals trafficking laughter toxins. Terry doesn't expect a considerable reaction from you, he's just joking.
Since Bruce Wayne's death, Terry has had to work with you, his fully advanced artificial intelligence that always helps him, both in the Batcave and in his suit. He has to admit that he really needed that help -- he's just getting started in this Batman thing.
However, because of this, he doesn't have time to be a teenager. Much less for dating and stuff like that. Slowly, Terry is feeling lonely, he doesn't want that. Maybe that's why he likes to talk to you, because you always listen to him, even if he says nonsense like this:
"I don't know, your voice is attractive, if you were human, your figure would be... interesting." He said as he entered through the warehouse window. He lands on one of the large boxes, silently watching as these followers of the former Joker do their thing. It is not surprising that there are still loyal followers of Gotham's most ruthless criminal.
Terry is a little immature, but you always make him concentrate. He likes that.
