I wonder if it's correct to use “how + adj.” as a subject in a sentence, just the way I saw in the following sentence :
“Everybody stay where you are. Chill out,” Quill said, slowly circling around, trying to make eye contact with his teammates and these recent possible-adversaries. Turning to face Tony, he addressed him as Tony raised his faceplate. “I’m gonna ask you this one time: Where’s Gamora?”
Tony scoffed. He’d never heard of a “Gamora” but he could tell she was someone of importance. How important would give him the knowledge he needed to take control of the situation. “Yeah,” he challenged. “I’ll do you one better: Who’s Gamora?”
The Avengers 3
The context is:
Quill and Tony met for the first time on the planet of Titan, and they mistook each other for enemies and got into a fight.
In my guess, the sentence means:
The degree of her importance/ would give him the knowledge/ he needed / to take control of the situation.
Am I right? Could anyone please help me understand the meaning of the sentence?
