So, the credits of the HD broadcast are messed up again... but with the "next week on Young Justice" promo, they make sense.

What's in the promo? The Team (mostly Wally) fighting Vandal Savage in the snow. Wally has a backpack. The credits of the episode list some familiar faces:
 * Brick returns.
 * Steve Blum as Vertigo and Rudy West
 * Hugo Strange returns
 * Nicole Dubuc returns as Iris
 * Bruce Greenwood as Pieter Cross - better known in the comics as Doctor Mid-Nite
 * Cree Summer as Mary West and Mattie Harcourt. Mattie was a Supergirl (Linda Danvers) supporting cast member. She's a medical resident.
 * Ariel Winter returns as Perdita, from the Showcase.
 * I kinda miss George Eads as Flash. It's supposed to be a Kid Flash episode and he's got no lines?

Now... based on the logline, and the main enemy (that rumor was right, apparently) it made me think...

Pieter Cross is a doctor. Mattie is also medical. The first issues of Flash Volume 2 (with Wally West as the Flash) involved a storyline where he had to transport a donor heart cross country, and he was opposed by Vandal Savage in that story. In the snow...
