I think Nat's reactipon will be the same as in Man Down, where Eric will be all that she can think about, however instead of working on a case she'll probably insist on helping to find him (hopefully she will be the one to find him). Which brings in two different and interesting EDeN story arcs.
First when she does find him will it bring about the revelation that Natalia is the woman of his dreams and all that other good passionate EDeN stuff from season 4 when you didn't need to show a couple doing couple like things like the other couple we know of.
Second (and bear with me) Is that since the Russian Mob was stalking the team and Natalia is the only one who hasn't been abducted or injured, I wondering if some one take her or some things happens to her if Eric will save her.
Lets say Calliegh finds Eric and in the maylay of checking over Eric something happens to Natalia. Now knowing Eric he won't let any woman ESPECIALLY Natalia be harmed in any way (please recall Nick and the time the suspect grabed her arm).
So if she gets kidnapped then Eric an come and find her (playing his best role as her knight in shining armor)
. Now when he finds her there can be a ture passionate, loving EDeN moment, hopefuly an embrace or a kiss :devil::drool:that will definately beat out that other one.
It's kind of hard to expailn but you can use your imaginations for how he rescues her.:devil::devil:
Now the only problem I see with the second one is that no one knows who the leader or the head of the Mob is since Sarnoff is dead, unless the orders are comming from a "big boss" in Russia.
Anyway those are my thoughts at 3 something in the morning :lol:. I HOPE it made sense.
