☄ If he unhooks a person, they'll go into a sort of withdrawal. The person will be intensely ill, but if Venom knows basic cpr, he'll be able to keep them alive. At this point, he can do a few different things. He can contact some friends on the Moira for help, leave and ask for help and come back later, or try to get them all out on his own. It's up to you to decide which he'd try to do. If he tries to take them all out on his own, he'll come across staff, and there will be a fight. If he asks for help, he'll have to hide somewhere until assistance comes. If he leaves and comes back, he can bring enough help to get all the victims, and then they can 'shut' the place down. However you want to do it, just let me know if you need more info.
