After Optimus Prime died, Sam and the others escaped, the conversation around the campfire at night

Sam: I messed up, I’m sorry

Bumblebee : You know, you are the person I care about most in my life. As long as you need me, I will never leave.

Sam: He died because of me. He came to protect me, but he died

Bumblebee: There are some things you can't change. Only in this way will his sacrifice not be lost. Meaning...Hallelujah...

Sam: I won't back down this time

Bumblebee: You are their only hope

Mikayla : You’re not coming, are you?

Bumblebee: Sam, if we want to change our destiny, we can’t count on God’s will...
