Cu chullian attempted to keep a vile tase of upchuck in his mouth when he saw a horrific beast heading towards his allies and with content, as if it had set only to kill them. HE knew well without his weapons he'd be destroyed but he had to help his friend. "malice, drop me, drop me now" he said having a sudden epiphany. If charak was a monsterous beast than cu chullian would just become a beast to counter the wolf before him, his raidstad would have to work out, he wasn't really thinking about what happened if he failed.
