In the universe of Resident Evil, where outbreaks are a regular occurrence, staying inside and as far away from people as possible can actually be a pretty good character trait. Then again, when zombies and B.O.W.s begin prowling the streets, trying to survive without any assistance can end up making things a little trickier than they need to be. Being an introverted Resident Evil character therefore comes with its own set of pros and cons, but it does also help to add a lot of reliability to these individuals too.
