Just you wait - 20 chapters from now you're going to find the perfect reason to bring Evil Kath's Sergio 2 back, and you'll realise he had a portable teleporter (probably from Doctor Who, but they're not uncommon) all along. ^_~
Given the way the story's going, I won't be all that surprised if an entire fighter squadron of Sakuras shows up one of these days...
I'm pleased to hear Sergio isn't the nexus of the WWA; it leaves far more opportunities for speculation on my part. :D I feel like the fact that multiple versions of him have shown up suggests he is a nexus of some kind, though. Purely speculatively, perhaps people whose timelines intersect meaningfully with multiple canons have a greater 'weight' in the WWA - meaning PPC agents would have an inordinately high chance of getting through, I suppose, as would commonly crossed-over characters (SuperWhoLock would have made it, for instance).
How do you feel about WWA fanfic?
"This is not cool, Constance; this is distinctly not cool."
"Calm down, Lou." Constance Illian-Sims shifted position, not that it made the metal bench any more comfortable. "It's just some sort of PPC malarkey. Feaminte will find us before long, and the Sheaf will go clonk the SO round the blossom until he fixes it."
"It's not, though!" Constance had never seen someone actually pull their hair out, but Lou was making a decent effort. "He's gone, it's all gone! I'm supposed to - my future is gone, Constance!" She stretched out an arm, reaching for something Constance couldn't see. "It's supposed to be there and it's gone."
"You're just stressed," Constance assured her. "It's perfectly all right; I didn't expect to wind up in New York for no apparent reason either. But I'm sure Narto will take care of your daughter-"
"Nar might not even exist!" Lou snapped. "Don't you understand, this is all-" She ran over to the bars and shook them. "Detective!" she shouted. "Detective- Eru, what was her name?"
"Beckett," Constance supplied, "and you shouldn't really use the Name of the One-"
"Detective Beckett!" Lou yelled. "Agent Lisbon! You have to let me out of here! It's all gone horribly wrong!"
hS, couldn't resist
