We've reached the penultimate episode of Falcon and The Winter Soldier, which means the series finale is just one week away. Still, despite the clock rapidly ticking down, we've got plenty of mysteries and unanswered questions left swirling around the show to dig into--so many, in fact, that there's a real chance we may not get resolutions for all of them in only one episode. But the potential for a second season or any number of spin-off shows or movie cameos for the cast remains on the table, of course. This is the MCU, after all.

This week picked up in the aftermath of John Walker's homicidal meltdown. After a knock-down-drag-out fight, Sam and Bucky were able to wrangle the shield from him leaving him to return to the US for court martial. Walker is given an "other than honorable" discharge and basically left to slink off with his tail between his legs--that is until a mysterious newcomer, Contessa Valentina Allegra de Fontaine (Julia Louis-Dreyfus), arrives to make Walker a strange and inscrutable offer of support along with an apparently blank business card.
