Every female RE fan I’ve met in Japan LOVES Leon (And most of the Japanese men I’ve met love Leon too lol)
玩家：吉爾，快到碗裡來
也有玩家希望是艾達王（王阿姨）：
不過也有玩家推測礙事梨和艾達都會出現
Sherry and Ada probably. Sherry is the one talking to Leon, that tone of voice is 100% Sherry not Hunnigan, and if Leon is really infected and his life is on the line Ada has to appear. Where there's Leon, there's Ada, especially considering he is going back to Raccoon City.
I assume its Ada, but I wouldnt mind a Jill cameo. The 3make did her really dirty but to a certain age of RE fan she is the original series mascot and she's got more games set in Raccoon City than anyone else (....two.)
