Mjolnir

"Oh, Thor! There you are!" you call after him.

"Rainbow Sunshine, what a pleasant surprise!"

"I just wanted to give this to you," you explain, holding out Mjolnir. "Alpine was pawing at it and I didn't want it to get scratched or anything."

Thor's face falls, his jaw dropping. He looks around the room to see if there's suddenly anyone else witnessing this. "Did you - you just -"

"Well, I gotta go but say hi to Loki for me!" He takes Mjolnir from you, staring down at it in shock. You chuckle, tilting your head slightly, "You know, I always thought it would be heavier than it is. Weird."
