Uuuuuuta! 
So, when I saw Amarii's temper, I thought to myself, "Hmmm, I wonder if Uta would be up to RPing her with Sir Duke....."  
 ninja  I don't have a plot thread, mostly cuz things tend to just... come up for me, that and my life gets crazy on whims.  But maybe I should mention what I have in mind for 
Sir Duke Ro serai.
When I got him, I wanted to keep him with the intent of the court from the Masquerade.  I kind of see him as a retired soldier - he's got a harsh past.  His family was well and kind though they pushed him out to make a place for himself in the world (kind of like a noble officer).  He went out to the world, only to find it wasn't going to be a "easy" glory.  s**t happens... he's had run-ins with Kalona, skinwalkers, abusive mates, etc.  Much of it de-sensitized him.  Now he wanders, being the courtly gentleman...but suppressing his own pains while avoiding the 
scars left by the past. 
 ninja  I was going to offer him to try for Galahad's plot, except... I dun't think Sir Duke would eeeeever admit such feelings.  It IS something common for noble soldiers to have such things, but Sir Duke would just sulk and suppress that too xD
