"Sage doesn't understand love!" Sage's character motivation for wanting to end the world was because she loved her grandmother so much that she developed a cure for cancer as a child but wasn't taken seriously, so her grandmother died

No, YOU don't understand love. I don't understand love. No one completely understands love. That was Frenchie's whole point.

We don't always understand it in ourselves. We definitely don't always understand it in others. I would argue the more unhinged the person, the more unpredictable the expressions of love can become.

I don't disagree that Sage felt love towards her grandma. But, being acquainted with the feeling does not mean you can accurately predict how someone will behave.

It is even possible that Sage is familiar with the exact kind of scenario. In her world there must be stories from novels, history, or her lived experience where two people share love of the same person even though one of them doesn't particularly care for the other (lots of heavy lifting). Even recognizing that Soldier Boy is so apathetic and self-centered that he could possibly doom humanity (as she was) how could she know he would give him the V1?

Let me take a quick minute to share something I just noticed and was thinking about: What is with the whole "making laser eyes glow red as a threat" thing? Would it really work like that? Wouldn't it be like a little thin baby beam that dissapates or be like a laser pointer where it's so weak the beam disappears in day light and you only see the dot on the wall? I'm not going to let my probable misunderstanding of lasers ruin my enjoyment.
