I have a quest for which an NPC is following me. I did a few dungeons with it, but unfortunately at the last one it refuses to leave, just stands at the exit. since I need this npc later on, I'm a bit stuck on the quest. what can I do? I know there's a summon console command I'd be happy to use, but unfortunately I don't know the NPC's ID (any idea if I can look this up somehow?)

So far I tried:
-bumping it (it follows me around fine inside the cave)
-Waiting outside the cave

Open the console and clicking the NPC should give you it's ID.
