10 Terrible Friends Storylines That Should Have Been Cut
9. Danny And His Sister
We all knew Danny was weird from the offset (he was manipulative and he looked like a Yeti), but no-one was expecting this.
Danny was Rachel's neighbour and boyfriend for a period in season five, and things seemed to be okay, until the episode, 'The One With The Inappropriate Sister'. Title says it all right there, but it's a reveal that just seems to come from nowhere.
When Danny introduces Rachel to his sister Krista, it transpires the siblings have an oddly close relationship - the pair are physically playful with each other in public places, she's happy to wipe cake stains off his lap and it's later revealed they take baths together. While it's never confirmed the pair are sexually attracted to each other, it's clear they never broke out of their childhood intimacy.
With this particular storyline, you get the impression the showrunners were looking for a way to make Danny interesting. He was pretty boring on the whole, showing immature tendencies from the start, and he just didn't seem to suit Rachel, who by this point had matured into an independent working woman.
Bringing in Krista seemed to be a way of ending the pair's relationship in a dramatic way, but no-one really cared that much and the whole thing is executed weirdly.
