Sheesh, I finally start a new job than and the forum explodes. How am I supposed to keep up now?
Bella is sympathetic with the MC about being bullied, but she'll still distrust him unless you can bring her around in Episode 3. Admittedly, it's actually hard to fail, but it can happen, in which case she will tell Jill the MC isn't a good person (though still better than Tybalt). It changes Jill's date a bit, and it seemed to close off a relationship with Jill if the MC admits Bella was probably right about him.
Unfortunately, this seems to have been effectively obviated by Episode 5. Even if Bella didn't come around on the MC, she will allow him to comfort Cathy, invite him to call her Bella, and spend the night.
Which shower scene? The MC fondling Jill, or him kissing her after she peeks? Or both?
I really liked the kiss, and Jill's reaction seems within reason (assuming she does generally trust the MC). I agree the fondling bit in the shower is poorly handled, though. If the MC touched her breast and then immediately let go I could see her choosing to let it slide, but the game clearly establishes it goes on longer than that. It's probably just DPC trying to throw the Jill fans a bone (this is a porn game after all), but it does feel very artificial. That's why I skipped it on my Jill-centric run.
