Possible Spoilers:

Levi just seems to be suffering with every chapter ITS SAD. I love the Mikasa/Levi parallels, he saved her in the beginning and she finally gets to repay her debt. From what I’ve seen she’s been saving everyone in the chapter, best girl.

Why "Under the Tree" is actually a RivaMika song

This song is all the rave right now. And it's actually a good one that has Linkin Park vibes. But being a RivaMika shipper, I couldn't help but delve deeper to analyze the lyrics.

And what I found is interesting.

𝑊ℎ𝑒𝑟𝑒 𝑎𝑟𝑒 𝑦𝑜𝑢 𝑎𝑡? 𝑊ℎ𝑒𝑟𝑒 ℎ𝑎𝑣𝑒 𝑦𝑜𝑢 𝑏𝑒𝑒𝑛? 𝑇ℎ𝑒𝑟𝑒’𝑠 𝑛𝑜 𝑎𝑛𝑠𝑤𝑒𝑟 𝑡𝑜 𝑡ℎ𝑒 𝑞𝑢𝑒𝑠𝑡𝑖𝑜𝑛

Mikasa was wondering what happened to Levi and was unsure of the situation and where he is, so she goes to ask Floch. Sure, she also asked about Hanji. But there is a difference when a person's name comes first.

𝑊ℎ𝑒𝑟𝑒 𝑎𝑟𝑒 𝑦𝑜𝑢 ℎ𝑒𝑎𝑑𝑒𝑑? 𝑊ℎ𝑎𝑡 𝑑𝑖𝑑 𝑦𝑜𝑢 𝑚𝑒𝑎𝑛? 𝐸𝑣𝑒𝑛 𝑖𝑓 𝐼 𝑐ℎ𝑎𝑠𝑒 𝑦𝑜𝑢, 𝑦𝑜𝑢’𝑟𝑒 𝑎𝑙𝑟𝑒𝑎𝑑𝑦 𝑓𝑎𝑟 𝑎𝑤𝑎𝑦

Ackertalk. Where was Levi headed with the conversation and what did he mean? It still remains a mystery to Mikasa how she and Levi had a certain connection through the Ackerman history, and she never got to know more about it. And even if she did try to, the circumstances surrounding them did not allow the chance.

𝐴 𝑏𝑖𝑟𝑑, 𝑎 𝑏𝑢𝑡𝑡𝑒𝑟𝑓𝑙𝑦, 𝑎𝑛𝑑 𝑚𝑦 𝑟𝑒𝑑 𝑠𝑐𝑎𝑟𝑓

Eren is the bird, the scarf is the symbol of connection. But the butterflies...

Same color, on the same side (their left), and in the same situation where the Ackerman is looking at their host. It seems the blue butterfly is linked to the multiple timelines in the story. Could it be that Levi also has the butterfly since he is the only one who could save Mikasa in every timeline she creates whenever she chases after Eren? Like he already did in the manga (main) and Junior High timelines?

𝐷𝑜𝑛'𝑡 𝑚𝑎𝑘𝑒 𝑎 𝑚𝑒𝑠𝑠 𝑜𝑓 𝑚𝑒𝑚𝑜𝑟𝑖𝑒𝑠, 𝑗𝑢𝑠𝑡 𝑙𝑒𝑡 𝑚𝑒 ℎ𝑒𝑎𝑙 𝑦𝑜𝑢𝑟 𝑠𝑐𝑎𝑟𝑠

Sometimes it sounds like "We'll make a mess of memories" instead. But either way, if the cabin dream is indeed an alternate timeline, then it can go both ways. Levi called out to Mikasa, and as a result, did not mess up the manga (main) timeline. Or Levi calling her back to reality messed up her newly made cabin timeline. Both to save her and to end the war.

Besides, who are the people who experienced the same kind of scars? Both physically and emotionally? Levi and Mikasa. Therefore, they are the ones who are suited to heal each other, especially when the war is over.

𝑇ℎ𝑒 𝑤𝑎𝑙𝑙, 𝑡ℎ𝑒 𝑎𝑙𝑙-𝑓𝑜𝑟𝑔𝑜𝑡𝑡𝑒𝑛 𝑤𝑎𝑟 𝑇𝑖𝑚𝑒 𝑛𝑒𝑣𝑒𝑟 𝑠𝑡𝑜𝑝𝑠 𝑊𝑒’𝑟𝑒 𝑔𝑒𝑡𝑡𝑖𝑛𝑔 𝑜𝑙𝑑𝑒𝑟 𝑆𝑒𝑐𝑜𝑛𝑑 𝑏𝑦 𝑠𝑒𝑐𝑜𝑛𝑑 𝑏𝑦 𝑠𝑒𝑐𝑜𝑛𝑑

As mentioned, Levi and Mikasa experienced the same kind of scars and trauma since childhood, fought all their lives, and carry the burden of their heritage and origins. They got entangled in the war brought about by the cycle of hate that never seems to stop. And they're getting old for this shit.

𝑊ℎ𝑦 𝑜ℎ 𝑤ℎ𝑦, 𝑤ℎ𝑦 𝑜ℎ 𝑤ℎ𝑦 𝐷𝑜𝑛’𝑡 𝑦𝑜𝑢 𝑤𝑎𝑛𝑛𝑎 𝑠𝑡𝑎𝑦 𝑤𝑖𝑡ℎ 𝑚𝑒? 𝑊ℎ𝑦 𝑜ℎ 𝑤ℎ𝑦, 𝑤ℎ𝑦 𝑜ℎ 𝑤ℎ𝑦 𝐴𝑟𝑒 𝑦𝑜𝑢 𝑔𝑖𝑣𝑖𝑛𝑔 𝑢𝑝 𝑜𝑛 𝑚𝑒?

Who else in the story mentioned the exact words, "Stay with me."?

It's obvious that Levi is calling out to Mikasa so that she won't give up on the fight to help him bring down Eren. "Are you giving up on me?" screams desperation. A little close-up here to prove the point.

𝐼’𝑙𝑙 𝑏𝑒 𝑤𝑎𝑖𝑡𝑖𝑛𝑔, 𝑤𝑎𝑖𝑡𝑖𝑛𝑔 𝑓𝑜𝑟 𝑦𝑜𝑢 𝐿𝑒𝑡 𝑚𝑒 ℎ𝑜𝑙𝑑 𝑦𝑜𝑢 𝑢𝑛𝑑𝑒𝑟 𝑡ℎ𝑒 𝑡𝑟𝑒𝑒

Who did Mikasa actually wait for while literally being under trees?

Yes, it's Levi. She was supposed to distract the female titan so he can attack. But she was too amazed and she ended up staring dumbfoundedly while waiting for him to finish attacking. And ultimately wait for the opportunity to do an attack of her own.

And who actually held someone while being under a tree?

Honestly, I will never get tired of this scene, this moment, this screenshot.

𝑈𝑛𝑑𝑒𝑟 𝑡ℎ𝑒 𝑡𝑟𝑒𝑒 𝐼 𝑐𝑎𝑛’𝑡 𝑡𝑎𝑘𝑒 𝑦𝑜𝑢

Levi can't take Mikasa because she's always chasing after Eren and he knows how devoted she is.

In other lyrics, it says "I'll come take you" instead. And who always comes to take Mikasa? Rescues her from trouble and prevents her from doing anything foolish?
