Encounters. If I had to choose one during life or on my final hour, It would be the angel everytime. If I had to deal with the demonic one, I'd sit her down and file those toenails, fill the tub and use the whole bottle a Mr. Bubble giver her a full body scrub with a brush and lufa. Buff those horns. While I'd appear to be the servant pampering her, it's really my idea, though I know if I clipped a fingernail she would gut me alive, so dominate her safely. I'd also gift her really dumb shit, like an original Gameboy with Tetris, 4 rechargeable AA batteries, and a charger, Boxing gloves, a cheap keyboard, and a lute.
You really fucked up by not giving her a flute, a classic mistake when dealing with demons. Say goodbye to your entire spinal system.
