Why did Josh say this?

When Josh reveals himself as the Psycho to the others, he makes a remark about how things would go viral on the Internet because of, among other things, "unrequited love".

But what exactly would he be referring to? Both Chris and Ashley were fully aware of each other's feelings (Ashley even makes a remark about how they always kept dancing and talking around it) and Josh knew they liked each other. Everyone else was dating, so that'd be 'requited' by definition.

I kinda get the feeling that this line might be a carryover from an earlier point in development. Maybe Chris and Ashley's feelings weren't always written to be mutual, and one of them did not reciprocate?
