Of course the image can't be real. If Logan weren't already shaken by the warped corridors around him, his nose assailed with the stenches of blood, bodies, and gun oil, his ears filled with mechanical whirrings and snapping sparks...his enhanced senses would be able to tell from the audio that Hank's voice sounds just the slightest bit off, that the image's graininess masks a hint of CGI texturing where real fur and flesh should be.
But the nightmare world around him, so like the Weapon X facility after his escape...and the fact that the figure being tormented is Hank...
He's more than a friend. He's pack. Like Rems.
"...nnNNNOOOOOAAAAAAAARRGH!"
With a scream born of the most primal terrors, the most bestial rages, Logan's claws flash out in a spurt of blood and a flash of steel, and Logan runs down the hallway, without thought to his own safety, to Sniper, to anything but one thing: Find his packmate, and kill whatever's making him suffer.
