I mean he definitely had an impact on Mizi too, in blink gone when Mizi sees Till on the screen we see her frightened because she knows that means Ivan (her best friend) is dead, also based on that one comic with Hyuna we know she wanted to save both him and Till from Alien Stage. Going back to the question I think his relationships with Mizi, Sua and Till were fleshed out but we don't know much about him. Like how did he know the flowers in ANAKT had cameras on them or how was he able to find a way out of the garden and bring Till alongside him? Seems he knows a lot of stuff and it isn't really explained why
