...this is a moment in a second lift from FD, where Lena put wrongly her blade on Nikita's thigh, so coming out of the lift, she cut him (also Nikita's hand on Lena's breast is not looking like well done lift)
...another lift - the third from FD, but this time Lena moved wrongly and for about two seconds she sits on NIKITA'S NECK, not shoulders - she could break his neck and kill him if he wouldn't have so strong neck muscles.
...this is the third lift as well, this time Lena is out of balance and almost fell from Nikita's neck/shoulders
I&K's lifts look like the couple is still not comfortable in it and it can be very dangerous.
So maybe those distressing moments in I&K's lifts also helped an idea of having one lift less.
