[Arc 9, Chapter 22] - Trapping everything

In this chapter if Aldebaran really gets trapped than wouldn't rezero be unable to continue?

I know a about Aldebaran's full authority which is a spoiler till this chapter in the novel, >!Victim and Aggressor!<. I don't think any of the modes can save him in this situation if Aldebaran gets trapped for real without Felt's intervention. What will happen to the world then?
Most likely I think that Satella will try to retrieve Subaru but she is in a deadlock as of now and Subaru cannot use his authority.

What do ya'll think?
