I do like the idea of Juvia being assigned as Sion's on-and-off again security detail, and if in the in-between they kept contact through coffee breaks and small excursions... it would make for really adorable CR!

Juvia could even be temporarily assigned to him again, after he returns from Leith. He... went without really having supposed to deployed himself to Leith in order to help with the crisis there, and when he returns, it'll be likely that he's kept under a closer watch/lockdown by virtue of being a precious Company bioexperiment.

Let me know, though, what works for you. /o/ Maybe we can get a thread going with them before Chapter 3 drops!
