Yes after this last episode it does seem like the show might go down the romantic path for Lucy and Wyatt.
It would give Matt a chance to say that line, maybe as an exclamation of surprise when Wyatt finds out who Flynn is.
On the serious side of things, what’s the plutonium for? Power source? (They did mention Back to the Future this episode.) Explosive? (After 50 years, would it still be pure enough for that?) Chemical or radiological weapon? (Nahh, too ordinary a result for such a complicated criminal plot.) I’m guessing they need to sign an action in the pre-atomic era, to prove they were responsible, using an element that doesn’t occur in nature in more than the tiniest trace quantities.
