Anyone who thought the game would change after the big reveal last week was probably a bit surprised to be turned upside down and inside out again on Homeland, as "Achilles Heel" continued to twist and turn until another shocker arrived in the final minute of action.

Tom Walker is most definitely still alive. The series made that clear in the opening seconds. He is also pretty clearly helping the terrorists, something the sniper rifle in that storage center showcased. He also has an Achilles heel, which may or may not save America from another terrorist catastrophe.

He loves his family, and is probably suffering from the same inner turmoil we all thought was affecting Brody at the start of the season. Hopefully, some time down the road, the CIA can use Walker's wife and son to help stop him from doing something he may regret for the rest of his life... that, is unless he's 100% for this cause, which is a huge possibility.

The question will be whether or not the government can trust Walker's wife again, after she unsurprisingly warned her husband that they were tracing the call. It was pretty obvious they weren't going to catch him right then and there, but it was still impressive watching him scale walls, take out FBI agents and finally lure them into a mosque in order to get away.

That Achilles heel made for some serious entertainment, while Saul's just made me bored. His Achilles heel is the job, and I'm glad for that. If he didn't habitually leave home to go to work, maybe his wife wouldn't have left. Then, we might have been stuck watching that snooze of a story line for the rest of the season. Thank you!

Much more intriguing is the fact that Carrie's Achilles heel seems to be screwing her personal life up. Whether it is plain self-abusive behavior, or ruining something that could have been good with Brody, she continues to mess things up.

Sincere or not, Carrie and Brody had a connection at the cabin. The fact that he thought she was just doing her job - which is exactly what it started out as - put the kibosh on the whole thing, leading Carrie to ask "I'm gonna be alone my whole life, aren't I?" Yes, you very well might, and I'm interested in finding out.

Brody, on the other hand, seemed to be settling back into something normal with Jessica and the family, which was epitomized so perfectly as the four of them ate popcorn and watched Ice Age on the couch. In that moment, they seemed happy, but maybe in Brody's case, maybe it was because he knew he might soon have an opportunity to climb the political ladder.

I LOVE the idea that Elizabeth Gaines has plans for Brody's future. If Homeland is going to have any legs as a series going forward, Damian Lewis needs to be a part of it. If his Sgt. Brody is no longer a suspect for terrorism, what else is he? Hopefully he's a member of Congress.

Becayse he told the man who gave Walker the address of the storage unit that he's "through talking with Nazir," maybe it will be time for Brody to move on to new endeavors. Then again, maybe he will continue to do whatever he was going to do with Nazir, and being a member of Congress will only give him more power to do so.

Be honest: did you expect to see Brody sitting in that chair?

Will the man "tell [Nazir] it's over?" Or will Brody continue to be trapped in whatever situation he has got himself into? Whatever the case may be, Homeland continued to shine with "Achilles Heel." With great episode after great episode, this is turning out to not only be the best new show of the fall, but the best season overall during the past three months.
