He disappeared.
In front of Basil’s eyes, that man in the suit - who at the minimum was a fair bit older than everyone else in the room - had just walked through the wall. Through the… Door. Wall? Someone had said it was a door… Right, the man in the suit had described it as such. To Basil, though, it looked like about as much of a door as any other section of wall.
That being that it didn’t resemble a door at all. But maybe there was something those people knew that he didn’t.
…Up?
“…Up?”
Basil almost bit his tongue after that. He was in the dark, yes, he was invisible to everyone else, yes, but this was not an invitation to begin talking just because one of the strangers in the room began speaking. In fact, it would be wiser if he didn’t attempt any verbal communication with people he didn’t know if he wanted to stay out of dangerous circumstances, like being trapped in a concrete room with an eyeball head woman.
No. Don’t think about eyeball head lady.
However, communication or no communication, there was a point raised which could not be denied under this circumstance. He was on the wall, and he had absolutely no idea how he had gotten on the wall, or this far up on the wall, or the ceiling earlier. Slightly more important, however, was whether or not he was upside-down, as that would likely impact further movement.
Eve could likely see the reflective yellow eyes glancing about in apparent confusion as Basil traced the walls before finally realizing he could just look at the lightbulb socket as a point of identification. “Uh…” The eyes made brief contact again before staring up at the wall, the realization having been reached that he was, in fact, upside-down on the wall on what was likely a big, ugly patch of fungal mold. “I… I don’t-”
Basil started suddenly. His perspective - no, his entire orientation in the room - was changing. The most sickening of sounds had slowly begun creaking its way to his ears, and he could feel the room shifting upwards, the far end angling up as his ears suddenly made contact with the wall. The creaking turned into a moist ripping sound, and only too late the realization was made that he was about to fall, the mold he was clinging to having dislodged from the concrete surface and begun its descent towards the floor.
Within the microseconds that followed, Basil knew he had to move or else all was lost. His hand dove towards the wall he was leaving, easily cutting away the mold in a cloud of yellowish-brown fumes, his fingertips nearing the wall and swiping at the retreating surface. His feet had already fallen loose at this point, and his attempt at retaining at least one source of contact was all that could save him from falling flat on his back and being blanketed by the vile wall hanging that shortly followed. But in spite of his effort, he swpied just a moment too late. His claws barely touched the concrete as his last exasperating effort to save himself ended in failure.
For Eve, and for anyone else who cared to look over, there was an awful sound of wet mold disengaging from rugged wall, and a moment later there was a thud, which was immediately followed by a revolted series of coughs, as the mold came crashing down on top of him and mostly exploding into small wet particles and a massive cloud of vile dust.
