Maybe you could show Boba seeing the flare, but don’t show Boba finding her body and him taking her to mod parlor. Boba seeing the flare could be the set up, and then later in the episode it is paid off when we fade in from black and reveal that Fennic is alive, and that Boba saved her life. For all we know, Boba could have found Fennic’s body not long after Din left.

I know showing is typically better than telling, but since Boba explains how he saved her, you could just skip all of that, and it would help truncate the “movie” a little more too. Also, I think the mod shop looks a little low budget, so cutting it is a plus in my opinion.
