If you’re talking about root A, it’s a yes – but in the manga, it’s not being said actually about that. The last panel we saw him in TG is where he clutches on his rabbit mask – and muttered “ kaa – kaa –”
I’m assuming it’s Touka –but I don’t know. We don’t really have an exact answer for that but – maybe he does know. I just want them to meet again –but I don’t think Ayato going to lash out or fight her. We see how he meet with Banjou and we can say for sure Ayato really change.
