The doctors responsible inject themselves as well to try to capture the other guy before he can cause more trouble. One doctor is an alcoholic and he realizes he can drink all he wants and not deal with the hangover as he can time travel to another ancestor's body and not deal with the aftermath. The other doctor is a female and in present day she primarily uses a wheelchair. When she time travels, she no longer needs the wheelchair when she time travels and is in the body of her ancestors.
