The others would not be able to sense it as keenly as Ira did, but the moment he sees Ramza stand, he realizes something is off-- can smell the darkness of another emanating from the Hero long before he catches glimpse of his different eye color. A darkness that could only be hers.

Shit. They'd fallen for it, after all.

"That's not Ramza," Ira hissed, hidden blade retracting back under his sleeve as he said it. Of course. Of course that's what she'd do. Her own form wasn't enough, no, she had to go and do that too. "None of that was!"

"I-Ira?" Lin raced down the stairs to her Hero the moment the barrier disappeared, wobbling as the stairs shook. "G-guys, it's terrible out there, kupo! The E-Enterprise is ready t-t-to take you all, but we have to h-h-hurry!"

Ira nods, gesturing towards his Corridor. "Everyone, this will lead us to the Enterprise! If you can walk, carry someone who can't! If we are to survive to save our friend, we must go now. ... Unless you'd prefer taking your chances with the stairs or down below."

He keeps his Corridor of Darkness open for anyone who would prefer to retreat to the Enterprise, and will wait until everyone either passed through or decided to brave the conventional means. That and he is super worried about Saori at the edge, there.
