It’s the moment everything broke.
If you’ve watched Attack on Titan, you know the scene. Season 3, Episode 22. The ocean is just on the horizon, but first, there’s a ceremony. Eren Yeager kneels, takes Historia Reiss’s hand, and leans in for a formal royal kiss.
Then his eyes go wide.
He looks terrified. Shook. Honestly, he looks like he just watched the end of the world, which—spoilers—he basically did. For years, fans debated exactly what flashed through his brain in that split second. Was it just a crush? No. It was the catalyst for the entire final arc of the series.
The Trigger: Why Historia's Hand?
It isn't about romance.
Basically, the Founding Titan’s power is a lock, and royal blood is the key. Eren had the "lock" inside him, but he couldn't turn it because he wasn't a Reiss. By touching Historia, a member of the royal bloodline, he momentarily bypassed the "Vow Renouncing War" and opened a direct line to the Paths.
But it wasn't just the Founder acting up. It was the Attack Titan.
The Attack Titan has this weird, unique ability to see the memories of its future inheritors. When Eren kissed Historia's hand, the contact with royal blood caused a massive "feedback loop." He didn't just see the past; he saw the future through the eyes of his father, Grisha.
What Did Eren Actually See?
This is the part that trips people up. Eren didn't get a neat, chronological DVD of the future. He saw "shards." Specifically, he saw his father’s memories of the night Grisha slaughtered the Reiss family in the crystal chapel.
But here is the twist: in those memories, Grisha was seeing Future Eren.
When Eren kissed that hand, he saw himself—his older, Season 4 self—standing in the background of his father’s memories, whispering to Grisha to "stand up" and kill the children. It’s a mind-bending paradox. Eren saw the future because he saw his father looking at him from the past.
- The Rumbling: He saw glimpses of the Colossal Titans stepping out of the walls.
- The Betrayal: He realized he was the one who forced his father to become a monster.
- The Scenery: He saw that "scenery" he mentions to Zeke later—a world wiped clean.
- Sasha’s Fate: While debated, most experts believe he saw bits of the tragedy that would befall his friends.
It explains why he becomes so depressed afterward. Imagine realizing you’re the villain of your own story before you’ve even done anything wrong.
Why This Scene Is the Ultimate Turning Point
Before the hand kiss, Eren was a hothead who wanted to kill Titans. After the kiss? He’s a shell.
He stops smiling. He grows his hair out. He starts distancing himself from Armin and Mikasa. If you rewatch the series, you'll notice he never truly looks "present" in a conversation after this. He’s just waiting for the events he saw to happen. He's a slave to a future he already witnessed.
Kinda tragic, right?
He tried to see if he could change things. He even asked Mikasa "What am I to you?" in Marley, hoping for an answer that would deviate from his visions. When she gave the "expected" answer, he knew the timeline was set in stone.
Misconceptions About the Kiss
A lot of people think Eren saw everything. He didn't.
He was actually surprised several times in Season 4. He didn't know Gabi would shoot his head off. He didn't know exactly how the battle at the port would go. He only saw the specific memories he chose to send back to Grisha. He "spoiled" himself, but only with the highlights.
Actionable Insights for Fans
If you're looking to catch every detail of this transition, here's what you should do:
- Watch Season 3, Episode 22 side-by-side with Season 4, Episode 20 ("Memories of the Future"). You’ll see the exact moment the POV shifts.
- Look at Eren's eyes. Animators at MAPPA and WIT specifically changed his "eye light" after the kiss. He loses the spark.
- Check the Manga (Chapter 121). The "memory shards" are drawn as literal floating glass fragments. One of those fragments is a POV of Historia from the kiss, which confirms he was seeing multiple timelines at once.
The hand kiss wasn't a moment of respect. It was the moment Eren Yeager died and the "Devil of All Earth" was born.
