Okay, hey, sorry I never got to the whole relationships thing.
@sailboat - yeah, would not be shocked at all if our two charries didn't really jive. He's reckless, and shes more...ducks in a row, horse comes before human, etc. She will see him as immature and irresponsible.
@amiga - I could totally see our two charries getting along. They seem to have the same intensity and determination. Although they probably won't talk a lot (Wren's not the chatty type), I can see them having more of a comfortable ease around each other. They share high focus, so I would not be surprised if they ended up training together or something of the sort. Your character will probably be the one mine is most comfortable with.
@stories - I don't think they would have any issues. The only thing I can see coming up is that your charrie does a really fast sport that is over quick. Wren's sport takes forever. I could see them teasing each other over this eventually, haha.
@zigzag - although I don't see Wren really being an enemy to anyone, I do think she would grow a bit weary of your character. Wren values her personal space, quiet time, and lack of interaction. Your character would probably try to talk to her, making her uneasy and a little annoyed. However, if she can grow to accept it, I can see it developing into a tentative friendship. As well, I think Wren would grow to respect her intelligence.
@breebree - I could see some conflict coming between our characters. Wren is very aloof and withdrawn, but she does not like riders who are cocky. Especially if he tries to talk to her or hit on her.
If anyone has any other ideas or wishes to plot further, let me know. ^^
