I feel like Rogue and MrKnobb dont want to count Nikky out yet, and thats why they did the choice thing, even in S2 Ep2 ! I mean it had already asked me in ep1 of S2, and I had picked Vicky already (as it was true for all of season 1, I had like one single time I picked Nikky over her, everything else went to Vicky)... So I was confused why ep2 of S2 was asking me who I picked again... I was like "Your not gonna convince me to change my mind game, if those two are the main love interest my choice is set in stone !!"
I feel like maybe they had a poll to see which leading lady most preffered and Vicky steam-rolled her daughter, so since they didnt want to write her out, they kept trying to make her more appealing, in order to sway some slightly indecisive players. Which is a good thing, I mean Palmer went the complete opposite way, Heidi bitch-slapped Veronica in a poll 90-10, and he just wrote her out of the story making her a minor character instead of sharing half the scenes with Heidi based on choice...
Also despite my hate of NTR (not that I see it as that, but soem might), I actually kinda like the James x Nicky pairing, if she doesnt end up with Jensen, I wouldnt mind seeing those young-uns becoming a thing... Vicky on the other hand has no one, she is so unapproachable, that she will die a miserable cat lady if Mr. Winchester doesnt tame her fiery red-head'd ass.
