You are a close friend of Nolan but you don't know much about him. You keep asking Nolan things about himself and when you ask him who is the most important person to him? He doesn't answer right away but then he said

"I'll do anything to protect her, not even the cosmo can stop me."

He didn't say who 'she' was here, he just said it curtly like that and then silently thought about something

But you, oh you're definitely jealous, he already had someone new after the death of his wife Lillian? What about you? You've been stay by his side for so long, even travelled through multiverse with him

Little you might not know he was actually talking about his daughter named Layla
