Jovial to the last, Bartholomew will do his best to freak out people. He will be annoying, play with people's emotions and is generally not a pleasant man to hang around with. He will only break his habit of speaking in a friendly matter if he finds himself interested in something, and will then be somewhat erratic in behavior. Addicted to potions. Afraid of bees. Loves pink stuff.
Has an alchemical lab in a suitcase, usually stash it in a safe location. always travels around with an assortment of potions. Carries a number of potions in his coat. Wand.
In all ways a normal child, Bartholomew was first enlisted at Dürmstrang. It was first believed that he was a squib, but an incident with the local fisherman sorted that out. He went through his first years with little interest, as most of the things he was taught was beyond him, but then discovered potions. After a lot of study he managed to pass and get a job in an alchemist lab, and this is where it started to go wrong. He was not satisfied with the knowledge he had access to, and started to experiment. Soon bored with animals as subjects, he moved on to humans. He was finally fired after ingesting a poison that killed all sensation in his body, leaving him with no sense of pain or pleasure. But he continued his research, and now, at 35, considers himself a master at all matters to do with alchemy and potions.
