Honestly, I feel like Flash should have had a bigger role here. Since they were exes, there was quite a bit they could have filled in here regarding their previous relationship. I’ve never pegged Flash as being stupid enough to not notice Sunset’s nastiness and their conversation in Legend of Everfree kinda proves that there was more to them than just dating because they were popular (“Come on, Sunset. We used to date. I know when something’s bothering you.”)
 
That being said, if they went that route they probably would have had to have give Trixie’s role to Flash, so that’s probably why they did what they did. It sucks because this seemed like a good moment for Flash to have another major role, but Trixie was amazing here, so it’s hard to complain.

Yeah, I expected Sunset to have an especially bitter encounter with him since they’re exes.

I think he need use a pacer.
 

I wish he had done more than just make cameos, but maybe he’ll get a bigger role next time.

Don’t think I didn’t notice you there FLash
