Black Shadow and Ashla have that thread to do. Shadow is contracted to kill Ashla under an alias he doesn't know her by. He is sent with another archer to do the job. Black Shadow realizes that it is Ashla, but can't call of the mission in time, the other archer gets het. He hits her where it's not fatal but has poison arrows. Shadow kills the other assassin, and talks with Ashla, she dies with him holding her, Felicity watching

I still would hate to see Ashla die permanently, but if that is what you wish then so be it!
