Pixie won't shut up

As soon as the fight starts, the pixie starts their "Won't you help me? Set me free". Once the fight us over, I examine the lantern, it shows there should be an action icon to examine it, but the icon isn't there. I've passed it around to all the characters. I've taken a long rest. I reloaded a save and tried the fight over, only to get the same result. Any suggestions?

Note I did not get the dryder 's lantern. As soon as that fight ended, the Harper had it. Do I need to go back to there and try to loot that one? That's like 4-5 hours of game time ago. 😫
