Wouldn't that just make it stronger or do nothing at all? What if you make it multiply or something...?" Oh... Then we can make them all bleed! Let him do it! "No... We have to let him do it, but if that thing multiplies, I'm leaving this house... I'll probably close the door and try to keep it closed too after a minute so at least some of us can leave and not get... Controlled, or parasitically eaten or whatever the heck that thing does..." He grabbed his scythe from nearby, readying it in case something happened.
