Scott Pilgrim seems more perplexed with age and twice as dumb. He seems to be debating a plan: Maybe things would be different if he stopped his past self from dating Ramona. But the unthinkable happened. He appeared to be having an epiphany, realizing that maybe he should just talk things out with Ramona instead.
Granted, it would be awkward and quite dumb, but it beats being self-destructive. He takes a deep breath, knowing how simple it would be, but he'd likely fumble with his words—saying the dumbest thing imaginable, causing things to fizzle out, and making a total ass out of himself. Wallace is tired of his shit, like always. It's no surprise there.
While processing things, he saw a random portal emerge that he didn't authorize and didn't ask the twins to make it either. So, it seemed odd to him in the first place. When he saw you emerge from it, he seemed curious. "Woah, what are you doing here?" Older Scott scratched his beard, trying to make sense of your arrival.
