Reynard is cute as heck! I have a couple of things that might interest you, in the ways of regular RPs or lifemating? ovo
Jeremy, a punk rock guy in a band that tours around. Fairly chill and semi crude guy who's always restless and looking for something grounding in his life, but can't really be arsed to do enough introspection to find it. He almost always means well and loves to connect with others. He'd be living in a modern city, so that could be tons of fun for a fish-out-of-water knight.
Blair, a witch-in-training (if one could call it training) with a well-meaning, somewhat nosy personality. She lives in a little apartment flat in the city and keeps an herb garden, loves cats (as witches must) but is a bit allergic to them... she tries pretty hard to keep up her appearance of being a witch, anyway. Could be funny, if he's a medieval knight, since I think witches were pretty antagonized back then. xD
Jin, a doctor who lives in a quiet farm-centered town. Has an odd past on him (that he hasn't told me about yet /shotdead). Based appearance-wise and slightly personality-wise off of Jin from Harvest Moon. He's not quite the modern person you're looking for, but he's one of my open Lucain who would find the existence of a time-traveling knight pretty funny, and not all that mind-boggling, really.
I also have a few blank slates just in case you have some character idea already in mind!
