Bumping this. Just got to this quest and I'm getting stuck in the same place. Looking at some videos, after the scene at the bridge, we're supposed to get another short scene as we exit the Isle of Angels, but that isn't triggering for me.
I'm also on the latest patch as of writing (13.5.7), so the bug hasn't been fixed between versions.
UPDATE: So the quest isn't bugged, just oddly ordered/written. The escort section actually needs you to trigger 5 events:
+1 on accepting the quest
+1 Triggering the event at the restaurant
+1 Visiting your yacht in the docks in the east of town
+1 Attempting to cross the bridge south of the Pokemon center (this is the one I missed and presumably the others here too)
+1 Talk on the bridge on the Island of Angels
(Weirdly, attempting to enter the museum doesn't count, despite the southern bridge one counting )
Only then will Odessa give you the prompt to bring her back on exiting the Isle of Angels.
