I was actually going to suggest maybe Kimblee and Xion meeting? Though maybe not now as she's currently in Kanto. Somehow. With tension maybe as she's a PGC and he's a Rocket, but he seems friendly enough?

Or maybe Korra and Tokiomi, however that would work. Or Xion to Tokiomi because she likes helping others if Tokiomi would need any help.

Or Saber/Extra and Tokiomi. Because red.

... yeah, you see why I was struggling a bit? Sorry!
