Alex isn't patient. J can't have gotten very far down the stretching corridor before his door and everything in front of it blasts inwards, carried by a concentrated gale. It doesn't go clear across the room or anything, because the cement blocks are damned heavy, but several feet is still plenty of room to allow Alex to stride in unobstructed.

If J happens to glance back, he'll see Alex with a sheen of sweat on his face, staring at his hand and then at the wreckage with awe. He starts laughing again, loose and exhilarated.

"Holy shit."
