看来之前的猜测。。。不过这是我唯一找到的东西

有评论给出了神鹰曾经和Zeta有关系

某个以Red开头的网站有人将其与国际社会对比

MIGHTY EAGLE: Zeta?
RED: Who is Zeta?
MIGHTY EAGLE: The leader of the eagles. Do one of you has been trying to destroy our island, and my ... ex-fiancée.
CHUCK: Wait, what?
RED: Did you say fiancée?
COURTNEY: Fiancée?
RED: And you're just telling us this now?
MIGHTY EAGLE: Better late than never!
(MEMORY)
MIGHTY EAGLE AS NARRATOR: It was many years ago. In the 1990s, she was the smartest girl in school, and I have an incredible sense of fashion.
MIGHTY EAGLE: Whoa!
ZETA: E ... (IPA: /e/)
MIGHTY EAGLE AS NARRATOR: It was lover (???) the first sight.
ZETA: I've missed you?
MIGHTY EAGLE: Ha, ha ...
MIGHTY EAGLE & ZETA: Oh!
ZETA: Ha, ha ...
MIGHTY EAGLE: Ha, ha ...
MIGHTY EAGLE AS NARRATOR: She was the best thing that ever happened to me. And since I wasn't quite ready to (???) for life.
MIGHTY EAGLE: Oh, wow! (???) engagement (???) ?
MIGHTY EAGLE AS NARRATOR: Naturally I am ...
(LIGHTNING)
MIGHTY EAGLE AS NARRATOR: I've .. I've abandoned her.
(END MEMORY)
SILVER: How could you leave her (?) like that?
MIGHTY EAGLE: Because I ... am a coward. Maybe you did know that about me.
SILVER: Well, actually ...
MIGHTY EAGLE: I assume she's been heartbroken ever since. It's all my fault.
BOMB: So this is fiancée (?) we're talking about.
MIGHTY EAGLE: You know what? I just remembered...

What we know now:
b&p build a submarine to eagle island but mighty eagle quits for that reason.
Red and silver get caught, while others disguise themselves in a eagle shell.
zeta finds inhabitants on the two islands don't evacuate as the team have given them confidence
finally the island is destroyed
mighty eagle marries zeta
information is sufficient now for me not to worry about their fate. now i just need to wait the full movie and explore the details.

What would the offspring of Mighty Eagle and Zeta look like?

LEONARD: Each of you has been selected because you're the best in your field... that we could find. Your skills will be put to the test, facing this! As you can clearly see this is a vo...
RED: Volcano! Volcano is what my... assistant was going to say.
LEONARD: Assistant?! You'll be assistant!
SILVER: Actually, it's a composite volcano. You can tell by the height and the clearly apparant white(?) clusters.
RED: OK, forget. I said volcano. This is a, em, it's a superweapon!
BOMB: Where(?)? 'Cause it looks just like a volcano.
LEONARD: Yep, and he is the (???) part. This is their psychotic leader! (Showing a selfie of Leonard) Uh, (???). (???)...
COURTNEY: (???).
RED: Em! This is their psychotic leader! (Showing Zeta)
MIGHTY EAGLE: Ummmmm... Ahhhhhh!!!
RED: Whoa, whoa, hey, buddy, do you know her?
MIGHTY EAGLE: What? Me? No, no! Definitely not! Absolutely no! Never seen her before. In my life, who is that? I don't know!
RED: Uh, terribly convincible.
(???)表示没听出来
(?)表示对听出来的东西存有怀疑

剧情已经挂上英文wiki了

FB上找到了8L的片段，其实是官方转载过的。Ytb上也看到了

然后还看到了……

vent clusters，喷气口群

“难道你不知道热稳定乳化剂吗？你只要用聚丙烯酰胺加强两种材料之间纳米颗粒和表面活性剂的结合度就行了。”
“What? You've never heard of thermal emulsifiers? You just gotta get a polyacrylamide to enhance the nanoparticle and surfactant association between the two materials.”
——Zeta
按照wiki所说，聚丙烯酰胺确实有热稳定性，其有乳浊液的形式但是没说它是乳化剂
剩下的也看不懂了
