Impulse: Which world?

Only a couple weeks ago, Iris West chose sides and went over to Earth-Skank. As this new Crisis ramps up, her daughter's back, and she's rejected her mother's lifestyle and cleaned herself up!So who will win this interdimensional custody battle? Max Mercury, former reject of Earth-X, now guardian and mentor of Bart Allen on Earth-1? Or his mom, descendant of an Earth-1 refugee currently residing on the futuristic hedonist paradise of Earth-69?

Small town, or big purple city? It's Bart's choice! But he has to choose well, cuz one of those Earths might not be around for long...
