Another one of those "just because I can" threads, I guess.
When you dig into your past in search of a memory to face a present situation, roll +memory. On a 10+, you did it flawlessy back then; thell the MC how and take +1 ongoing. On a 7-9, you remember something useful, but it's complicated: the MC will tell you what happened and offer you a different course of action to reach the same objective. If you do as he says, take +1 ongoing. On a miss, you revive a nightmare: the MC will tell you what happened and you'll take -1 ongoing.
For example, Katarina is hiding behind a corner looking at Brush, the Dome of Pleasure's bouncer. She wants in, he doesn't. "Of course I dealt with him before," says the player, and she rolls the dice.
On a 10+, she tells me "He has a thing for redheads; I just have to shake my boobs a bit and he'll let me in" and takes +1 to seduce Brush until the situation changes.
On a 7-9, I tell her "The last time you tried to convince him, it was fruitless, but shortly after that you learned he's a thing for very young girls; if you tell him the location of Joy, maybe..."; if she's willing to sell her young friend, she'll take +1 ongoing to convince Brush to let her him.
On a miss, I tell her "Yeah, he has a thing for redheads. You know it since he spiked your drink and had his way with you on the kitchen floor" and she'll take -1 ongoing until she can prove to Brush (and/or herself) that he can't take advantage of her anymore.
