"Friends" might be stretching it. However, Regulus does not dislike Five.

If you'd like to jump on one of my OPEN thread starts for the travels, I'm down with that. OR, we could come up with something else - maybe she notices Reg talks to Five more than a few times? (looks suspiciously friendly?) and investigates whilst riding/setting up tents/on a shared watch? (I'm just spitballing here - very open to suggestions.)

We can also plot on plurk if you'd rather.
