archer sea tunt part 2 lana captain murphy fx 'Archer' Season 4 finale preview: 5 things to know about 'Sea Tunt Part 2'“Archer” Season 4 comes to a close tonight with the conclusion of the two-part “Sea Tunt” arc that began last week.

“Sea Tunt Part 1” united the entire ISIS crew on board a ship owned by Cheryl’s brother Cecil (Eugene Mirman, from “Bob’s Burgers”) and piloted by his sarcastic girlfriend Tiffy (Kristen Schaal, also from “Bob’s Burgers”). And by the end we met Captain Murphy (Jon Hamm), a madman in an undersea lab threatening to wipe out several American cities with nerve gas missles.

It’s all resolved in “Sea Tunt Part 2,” along with a few surprises. Here are five teasers of what to expect — before we have to wait nine months or so for another new episode.

Because of course. (And as seen in the episode’s promo images, he sports the requisite ‘stache.)

Captain Murphy makes his demands: He’s a man who knows what he wants. But he may not know the best way to get it.

Pam has a sister and another secret hobby: We haven’t met Pam’s family yet, but an offhanded reference to her sister — Edie — could be laying the groundwork for that in a future season. As for Pam’s latest crackpot interest, let’s just say she probably really enjoys “Doomsday Preppers.”

But being stuck in the middle of the ocean with no mini bar in sight is a fate she probably wouldn’t wish on her worst enemy. Well, maybe Trudy Beekman.

There’s a major change in the personal life of one of the ISIS team: The writers drop plenty of clues leading up to the big reveal (and dropped a couple in last week’s episode as well). Watch closely and you’ll figure it out before Archer does. Probably.
