As someone who has seen both movies, (iron lung three times) here's a few things i see ppl get wrong/ misunderstand:
Simon is missing his left arm, up to the shoulder. Like at the bicep.
Simon is not just a eel, he's fused with the seed and explodes into a tree.
The seed was on the left arm, fused, reversed Pinocchioed him, and got ripped off.
He kills Elli by exploding into a fucking tree.
God gave him prophetic visions and fucked him up. Promised Simon would live, and like a Genie, didn't specify how.
Also some time manipulation bullshit was happening.
Homeboy is played by Mark(iplire), who is Korean. (Draw him Korean you cowards /j)
Simon would not necessarily be impressed/ emotinal from looking at stars. In a flashback he's seen stars before, but knows they're ghost light. He would be grateful being able to see them again though.
He WOULD be very emotinal about any plant life. He found a new will to live when he found the little seed. He had a breakdown when the little charm cracked.
His "job" on Eden was to nourish the last tree with the people he killed. Hence his nickname.
There's a lot symbolism regarding trees (the hull window crack)
Simon is resourceful and smart! Like smart smart! Let him be smart woth Rocky and Grace!
Yes, Simon can be aggressive, but is only in situation where his life is threatened. He's also remorseful. He's apologetic and does want to make up for his wrongs, even if it wasn't his fault.
Like Simon, Grace did not go down without a fight. He ran, yes, but when he was being sedated he shouted how he would sabotage the mission. Do everything he can to make it fail, just so the wouldn't risk putting him on the exhibition.
He is incredibly brave. He did a space walk without training. He trusted rocky that he wouldn't explode in the space bridge. He CLIMBED ON THE BURNING EXTERIOR OF THE HAIL MARY TO RETRIEVE THE COLLECTION DEVICE.
Grace is not a crybaby. He crys for very real, reasonable reasons! When he was betrayed? When they found a solution to save their stars? When Rock gave him a way to return to Earth? It would be weird for him NOT to cry! (Edit: person in the tags you're so right)
He would be scared meeting Simon, but he would not be a coward.
They BOTH have a "This is bigger than me" mentality. They both risked everything to ensure the survival of humanity. They were willing to die.
It's not selfish just wanting to live.
I don't think either of them would have a problem doing anything to survive. (Eating the Taumoeba or Me-burgers)
