Keiynan Lonsdale will not be a series regular on Legends Of Tomorrow season 4, despite the fact that Wally West (aka Kid Flash) appeared to enjoy being a part of the Waverider crew in season 3 of The CW’s time-travelling superhero show.
Lonsdale, according to TV Line, will be appearing in The Flash season 5 episode 1. This makes a certain amount of narrative sense, considering that Wally popped up in Central City in The Flash season 4 finale to welcome his new baby half-sister – Jenna, the daughter of Joe and Cecile – into the world.
It remains unclear where Lonsdale will fit in The CW’s Arrowverse after The Flash‘s season 5 premiere. TV Line assures us that his character will remain “alive and well”, although we don’t know which show will be his home.
Perhaps a ‘universe regular’ contract, allowing him to appear on any of the shows as and when they need him, would suit Lonsdale best. John Barrowman, Katie Cassidy and Wentworth Miller have all had deals like that in the past, and it worked fairly well for their characters (Malcolm Merlyn, Laurel Lance and Captain Cold).
But yes, as it stands we don’t know where/when Wally West will appear after the first week of The Flash‘s next season. He won’t have the same series regular spot on Legends as he had last year, but that doesn’t mean he can’t guest star.
We’ll keep you posted as we hear more.
