I wouldn't even need ending slides, they could do an old school rpg thing where they show a clip of the grove, life there, a clip of the tieflings doing their thing, Alfira playing on a rooftop, Halsin heading out into nature, etc. All with the narrator giving short summaries of what they did, are doing now.
The ending started great, with the baldurians fighting back against the dying mindflayers, and then cheering, but then the companion stuff was just..brutal.
