Aside from Joel (Pedro Pascal) and Ellie (Bella Ramsey), the pair have one of the closest relationships out of any of The Last of Us characters we meet in the TV series. Unfortunately, though, Bill and Frank’s relationship is cut short when Frank develops a debilitating illness.

What was Frank’s illness?

Frank’s illness is never revealed, but we can infer from conversations had with Bill that it was severe and painful. We also know that as it progressed, Frank came to rely on a wheelchair to move around.

Bill seemed to believe that if a doctor came along, something could be done to treat Frank, but we can probably put this down to him wanting to keep his lover’s spirits up. Frank likely had some progressive disease like cancer that was exacerbated by a lack of medicine.
