If we went back in to T-Virus spin offs, Sherry is one of the best candidates for becoming relevant again. I don't think she can become infected even if bitten. A lot of the lore circles my head and drips right out of my ears, but I think that is a fact. We spend so much time with the same characters - I am glad spin offs exist to shed some spot light on what other characters are doing. Where the hell is Rebecca?
