Sorry, but this is a spinoff I definitely don't need. Unless it's completely changed. I didn't hate it, but I also didn't see anything that made me go, "yes, give me more ASAP." Give me FTA with, at most, recurring Canaries (and even then, not necessarily always Laurel and Dinah).
Needed a lot more Mia/William. And that ending makes me think that at the most, BL would be recurring in a spinoff series and Mia might be searching for him for at least part of the season. Also needed more Connor. And Zoe.
Maybe Oliver decided to give Felicity a Canary-free life by sending Dinah to the future to be in SC when it went to hell again and knew Laurel would follow and figured they could be helpful then and his wife could live in peace at least for a little while.
(Also, if the spinoff is ordered, it should be interesting to see if KC and KM continue to only promote their stuff on social media. I glanced at their tweets tonight and was really just so amused. Their preferences are so obvious.)
