[Armin looks more thoughtful and a little less desperate, at that - it's a perspective he hadn't quite considered before. After several long moments, he slowly nods.]

I understand. We might not be able to deal with him directly, but we may still be able to defend ourselves, if they think to take us unaware.

[He considers that for a moment longer.] While I can't say none of the Trumps are working with him... I feel like it's unlikely Rose or Psyche are. So it may still be worth the risk.

On the other hand... I almost wonder if there's even anything they can do. He infiltrated liminal space, their domain, and the telepathic network. You'd think that if they were enemies and they could have thrown him out, they would have.
