Ok WOW this episode delivered big time emotionally for me. Seeing Ollie, Wally and even Diggle in what is most likely the final Arrowverse crossover was really emotional. The action, comedic and dramatic elements all hit so hard. Sendhil Ramamurthy returning as Ramsey Russo was great and that sitcom studio like segment was kinda creepy lol. The first Arrowverse crossover was a Flash/Arrow crossover so it’s fitting that for the last one is a team-up with Barry and Oilver. Anyway loved this episode and like Web-Head said hopefully the series can end on a high note after how mixed this season has been so far. Next week does looks equally as awesome. Also glad that this was kinda a coda to Crisis On Infinite Earths so that was nice to tie that loose end up. As well as checking up on Felicity, Mia and William in the present timeline and Diggles family too. Everything with Wally was great too.
