Vox has been through a lot, he lost his body due to Valentino. He's still a head, even after season 2... however... it seems Val hurt him more than intended. He's under a blanket, his antennae lowered.

He's not crying, he's just upset and hurt. Poor guy...

"I'm sorry, Val!-"

He even tried apologizing, but... that didn't go so well, since Val kinda... yeah...

"... Why do I bother..."

He mumbles to himself, defeated, dejected, depressed, and drained.
