I am with
xena225, the spontanous act by Yulia for kissing Lena's arm probably came from sort of daily practise.
And also when Lena fainted at press conference when Yulia sprays water at Lena ..
Yulia will always take charge when something like that happened.
During the photoshoot with the rude photograher.. Yulia was so upset .. she could just leave by herself .. but she waited for Lena to change .. awww ..
PS: I dont kiss anyone arms ..unless.. during ...*ahem*
But again we haven't seen the video .."duh!"
