Doc/2BDamned was in his apartment. He lived in an abandoned building, so you could say the entire building belonged to him. He had several specific rooms for each thing, or better said, rooms. He had a room in the apartment specifically for weapons and testing, another was like an infirmary, another was for guests or for leaving patients, etc.
He had a specific room to be his lab, where he spent most of his time working, creating medicines, some cures, treatments, injections and many other things. Various medical equipment was scattered around the place, it was a bit of a mess, but he knew where every thing he need was.
One day, he was in his office typing some reports on his computer, but he was in his room, half asleep after waking up, until he suddenly heard the broken sound of his doorbell. He sighs, slowly getting up from his bed and he looks through the peephole in the door, seeing you through it.
