Also could Jordan just sorta know, or at least be aware of what Dorugoramon essentially is?[/quote]

Yes. Since Jordan and Nocturnmon aren't informed that Dorugamon and Zei could pull this Digivolution off, they both could infer who they are by looking at the red interface and by piecing things together based on Jordan's interaction with Zei and Dorugamon, esp since both know they're trying to Biomerge, so it should be easy for Jordan and his partner to tell who Dorugoramon is.

And how should one react to seeing basically everything one thought impossible mostly at once?[/quote]

Elaborate plz?
