I do not know Slav culture well. In Latin, in general, when a couple separates (pretty hard like them), it is quite rare that the woman touches the dick of the gentleman and that sir touches the pussy of Madam (even by play) and in front of friends!!
I do not think that either for the views: too late.
Only the Russophiles, understood, but as they never share ....
For me, either it's a moment of simple nostalgia (a form of farewell) or the reconstruction of something else, otherwise. I lean for the first, because the support of Dean & Candy only serves Drew.
