Oddly enough, two different endings were filmed for the Castle finale, with a cliffhanger set to wrap things up if Season 9 had happened; but since the show was cancelled didn’t, we got to see Castle and Beckett’s time-jumping, happier ending.
We may never know the real nitty gritty behind what went down, but at least we have Castle’s good years to look back upon.
It then looked like ABC might make a revamped Season 9 happen after Nathan Fillion’s contract was renewed, but the cancellation later came down as expected.
As fans likely remember, Castle was in the back half of Season 8, and while everyone was waiting to hear any kind of renewal news, the show announced that neither Stana Katic nor Tamala Jones would be returning for a ninth season, should one have gotten ordered.
