I actually did enjoy Katie's banter at the start of the game, back when it was something fun that the two of them shared together. But then the writer's changed it into some sort of weird compulsion that Katie couldn't control, and it became a negative quality instead of a positive one. Her jokes became overused, tired, and dull. Her dinner date should've been something unique to Katie, but instead it was just a poor imitation of Monica's date. She should've been helping us set Debbie up with Lily, or dealing with the aftermath of what we did to Natasha, or being anything other than a one track joke dispenser.
Katie was so much more interesting at the start of the game. She was a well rounded and believable character. But now she's just an insecure joke bot in desperate need of new material. It's so bad that it's affecting other areas of the game now. The setup for Debbie and Lily was very anemic, which makes the foursome scene seem like pure fan service. I triggered the foursome even though I had rejected Lily several times, had done nothing to get them together, and had Debbie angry with me because she refused to believe that I wasn't interested in Lily.
Francois was fun the first time, but the second one was a disaster. It was too repetitive, it happened too soon after the previous scene with him, it took up far too much of the night out, and it just wasn't clever or funny. The only good thing about his third appearance in the game was how short it was. I can't stand him at this point, and I hope he never returns.
