Grok couldn't help but feel some remorse for the ogre. He had seemed like a worthy oponent and an honorable one at that. The beast hadn't wanted to fight, that was clear. It appeared though that the evil corrupting this place though had finally taken its toll on him and he had no choice.
Grok moves to the body and kneels down. To others, it might appear that he's inspecting the remains of the ogre, but in reality he says a short and silent prayer for the lost soul of Logbrag. The others probably wouldn't understand, but he felt it necessary for such an oddly honorable opponent.
When the half-orc is done with his prayer, he does in fact look at the body and tries to learn anything he might regarding what had somewhat possessed Logbrag.
OOC:
Specifically, Grok is curious to know whether the body is decomposing like the cat, or if there is something different about it. The way I'm reading, it seems like Logbrags refusal to fully give into the "goo" might have spared his entire body from becoming a black puddle.
