Red: Sophae created an illusion so convincing you all thought it was real and anyone who ran afoul of it thought they had died.
Drago fulfiled his quest during the Vamp crisis. Basically Scar's little rip in space time allowed his to do the mojo on Lelan and make her human again, via the immortal Micheal (Hay I can do cliche as well.) I thought it would make him more interesting if he had to care for a mentally disturbed wife than if he was a hard drinking unkillable warrior.
Plus I get to do the immortal thing in PtH.
