Are Leon and Ada the only R.E. characters that have ever gotten any play?

Let's review 0-5... in zero there was Billy pretty sure he had a thing for Rebecca but never made a move. Then in part one, almost positive Chris never got it on with Jill. Part 2, Claire and Leon are like brother and sister, so they would never. In part 2, Leon got a kiss from Ada(first romantic thing we see in the R.E. series. Part 3, Jill and Carlos pretty much have the same relationship as Jill and Chris, just friends. In Code Veronica there was something going on between Claire and Steve, but nothing really happened because *SPOILER* he died. Part 4 Ashley's Little slutty self TRIED to make a verplaats on Leon but he wasn't interested, probably on account of having to listen to her whinny butt throughout the whole game. Leon and Ada didn't really have a sexual relationship in part 4, but he did try to make a verplaats on Hunnigan but she flat out turned him down. Part 5, Chris has the option of Sheva but it didn't seem that that much was going on in that department. Wesker we see him start to get a little play from Excella, but I'm pretty sure Wesker is gay. I mean after all let's face it Excella is hot, she has a good form and lots of cleavage and in the first scene u see her, she's is rubbing her chest on him and groping his arms and chest and hitting on him, but he shows no interest, which means he is probably gay, since all he seems to want to do is talk about Chris. So, in conclusion, are Leon and Ada the only people in R.E. HISTORY that ever gotten any play?
