Okay, whilst it's cute to see Claire in a bubbly mood and it's a bit of character development to learn that she's got a talent for sneakily arranging stuff (including her brother's life, if he's being indecisive) this may not end well.
Claire's intentions are good: She feels that the only way to get Clinton out of his indecision loop and comfort zone is to put him in a situation where he has no choice but to talk to Emily. However, this could blow up in her face if Clinton does something stupid or says something hurtful because he's off balance. Then she'd be partially responsible for her best friend's heart being broken and her brother's nose being broken...
again.
So, looks like Clinton and Emily won't be present for #3000.
Maybe and maybe not. This could just be a jump-away interlude to explain exactly how Clinton and Emily ended up in the park together. We could go back to the other couple tomorrow.
Now, where are Marten and Claire going?
Personally, the thought that Claire and Clinton met during Claire's lunch break is fairly sound. She and Marten could be going back to the library as it could be Emily's day off.
FWIW, whilst I think that we'll be switching back to Emily and Clinton, it is
possible that we will be getting a set of update strips on the Claireten ship (especially if there has been a big time skip and Jeph wants to emphasise that in the narrative). However, as I say, I think going back to Emily and Clinton is more likely.
