Gen V Season 2 Ending Explained: Polarity’s Arrival Upends Marie’s Future

Gen V wraps its second season the way this universe likes it: big swing, lots of blood, and just enough plotting to make you side-eye every hallway at GodU. The short version: the kids face off against Thomas Godolkin, the school’s namesake turned puppet master, and it all comes down to who can outmaneuver whom before someone rips the roof off. Literally.

First, the history lesson: how Godolkin cheated death

The finale opens in 1967 with the lab fire that should have killed Thomas Godolkin (Ethan Slater). Instead, he jabs himself with Compound V mid-disaster and walks out with powers. So if you were wondering how a dead founder suddenly popped up with a plan and a wand of mind control, there you go.

The seminar from hell

Cut to now: a fully restored Godolkin invites the student body to a seminar. Surprise, it’s a trap. His pitch is simple and horrifying: cull the weak Supes, consolidate the strong. Yes, that is as messed up as it sounds, and yes, it quickly turns into a slaughterhouse.

Marie steps up, then gets shut down

Marie (Jaz Sinclair) comes in carrying a lot: the truth about Cipher, what Godolkin’s been doing behind the scenes, and the general realization that the adults are somehow always worse. She starts by making things right with Cate, apologizing and ultimately using her powers to heal her. Then she and the team gear up to take down Godolkin on his own turf.

The plan (and who does what)

• Marie, Sam, Cate, Jordan, and Emma recruit backup: Harper, Ally, and Greg.
• Cate opens a path for Marie with her abilities while Black Hole sneaks the rest into the arena.
• Ally manages to restrain Godolkin; Harper briefly copies his powers to turn his control back on him.
• It almost works. Then he surges, overpowers Marie, and hijacks her abilities, threatening the whole squad: Cate, Sam, Jordan, Emma. It gets ugly fast.

Enter Polarity, stage wall

With everyone on the brink, Polarity (Sean Patrick Thomas) crashes through the door and snaps Godolkin’s hold over Marie. That opening is all she needs. Marie resets, goes right at him, and ends it. No ambiguous cutaways here: Godolkin is done.

Where everyone lands after the dust clears

In the immediate aftermath, Marie, Annabeth, Cate, Emma, Sam, and Jordan leave Godolkin University behind. Polarity stays, which is... a choice, but a useful one given what he just proved he can do. On the road, Marie checks in on her sister Annabeth, and Annabeth decides to stick with her. Then the big universe handoff drops in: Starlight and A-Train show up, fold the group into the wider rebellion, and all roads point to The Boys Season 5.

Sister Sage’s very careful long game

Meanwhile, Sister Sage (Susan Heyward) returns in a way that confirms she is still thinking five moves ahead. She invites Godolkin to move into Vought Tower and hints at a plan to introduce him to Homelander — gently, so they don’t poke the bear. That’s the kind of strategic caution you rarely see in this universe, which is also why it immediately runs into a brick wall.

Godolkin announces his kill-seminar anyway. Sage hates it. She clocks the scars on his hand from overextending his control on multiple students at once and tells him to stand down. He doesn’t. Instead, he lays out a bigger swing: dominate Marie now, Homelander later. Sage draws a hard line — Homelander is essential to her Phase 2 — but Godolkin keeps pushing. The more he uses his power, the more the scars creep up his face and neck. It’s a literal visual of a plan burning through its owner.

Did Sage help take him down? Pretty much

Sage tries, fails, tries again. And when persuasion doesn’t land, she does something simple and surgical: she visits Polarity in prison and leaves the cell door unlocked. That’s not an accident. Polarity is the one super Godolkin can’t control, which makes him the exact counterweight the kids need. Free Polarity, break the puppet strings, end the seminar massacre. Clean, if not exactly subtle.

To be clear, we still don’t know Sage’s full blueprint. But Godolkin’s campus stunt clearly blew up the timeline she wanted, and her move with Polarity feels like someone steering the ship back on course. Consider that your bridge to The Boys Season 5: Sage’s Phase 2, Homelander’s role in it, and what this new student faction looks like under Starlight’s wing.

The bigger picture

This finale does a couple things that matter beyond the body count: it shifts Marie from reactive to decisive, it puts Polarity in a pivotal spot, and it draws a bright line around Sister Sage as the person quietly shaping the next wave at Vought. Also, it closes the book on Thomas Godolkin — who started a season as a ghost story and ended it as a cautionary tale about power you can’t actually hold.
