He frowns. That.. doesn't sound great. It would explain why they ended up in their worlds, yet are now back here on the platform, as if nothing happened in the first place. The train just never fully let them go to begin with. Which could be on purpose, but when Inigo sees the train appearing and reappearing in some sort of loop, he feels like it probably was a dumb accident.

"It probably doesn't know how to really untether us."

Which is really dumb, because maybe the train shouldn't have tethered them in the first place if it had no way to undo it, but.. still.

"It's not letting us in though." Inigo gestures across the platform with an arm. "The doors are locked tight. I've tried multiple times to open them now, but nothing seems to be working."
