That really shouldn't be happening. There is literally code in place to let you name the character (B1) I just looked at the build. So maybe your save got corrupted in some way. I'm sorry about that, but either try an older save that comes before the pool scene, or fast-forward the game again to that point. Otherwise, delete the build and redownload it. Perhaps some of the scripts were mixed up and overwrote something from a previous older build. In short, you should get a prompt that allows you to name the blonde that speaks in that specific scene if trans is off (Brenda is the default name).
