Webb

Dr. Webb was a psychiatrist at a mental institution that The Count was locked up in.

Season 1
In "Unfinished Business", when The Count came through the institution, he still had a large amount of Vertigo in his system. Dr. Webb was able to extract this and create his own version, with added chlorpromazine to make the effect stronger. He began selling it in order to make money. After some time, The Hood tracked him down and discovered the truth, that The Count was not the one producing Vertigo. However, he was given liquid Vertigo, which he used an antidote on. He later escaped and shot Webb in the heart, despite still slightly being under the influence of the drug.
