Well, where to begin ..... I've known Wil since he was just nub, or atleast I think I've known him since he first appeared in Ratchet waaaaaaaaay back when.
Will edit my full thoughts as it goes on. Yup I remember lots and lots of Wil.
First Edit: Here's a not so short summary of my roleplay with Wil; meeting my first character, befriending my first character, scaring my character out of Ratchet, discovering my disguised character, hanging out with my character, joining the Frostbrand, thinking my character was weird, having hostile relations with another character, getting two to three of my characters killed(of my choice of course, but still xD) meeting another one of my characters on the frostbrand he wished to kill. That was mainly Pre-restart. Post-Restart. Meeting up with another made up character of mine, getting another character killed, making another character hate him and want to kill him, 2 weeks of hell, breaking a ic friend of mine's heart, joining the heretic circus, working with the heretic circus.
I think that's all, think! There's definitely more that has slipped my mind.
Second Edit: I on the contrary don't think Wil needs a life-altering experience. I would suggest Wil one day would maybe think back on his life, think far back about someone he's forgotten about. Try to find them and go from there, maybe they'll hate them, maybe they'll try to kill him. Who knows?
Third Edit: Have someone roleplay a human brat that's supposedly his son that's trying to hunt him down, but Wilhelm doesn't want it, something that really doesn't alter his life but fuels why he's been afraid to settle down with someone, why he's always been after women.
The second and third edit were suggestions for future things, still I have yet to elaborate more on how our roleplay has been.
Fourth Edit: Okay so there's so much that I'd rather not spill the beans of so much roleplay, so if you need help remembering anything Wilhelm, or pretty much any help just PM me. If you do want me to write out all the rp I've had because of Wilhelm I'll type it up and PM you if you want me to.
