Interesting phrasing and it's a fair question too. Jason's never done time traveling or gone multiverse hopping but well, there's a first time for everything. Maybe he got accidentally sucked into a portal or something.

"Probably by universe or timeline. As far as I know, there's no Robin who uses a bo. And if you really do know me, then you should understand why I need to talk to him," he says, still cold.

Given where they are, he's not really interested in fighting this Robin in the same way he wants to fight Bruce. But he is ready to defend himself if needed.
