^ Hahaha I'm trying really hard to restrain myself from proving you wrong in that last video for SooSic.
Phew! Good thing I posted that vid instead of this one. I
know you will attempt to prove me wrong this time.
So who's hand was Jessica responding to? I'd like to point out that SY might know where are Sica's sensitive areas are. 10 years together would be a complete waste if they don't know certain things about each other that no one else knows about. Also notice the way SY is starring at Sica, like she was planning to do something to her while they're performing.

Okay, back to what I
really wanted to show. I could've put this on another thread, but I saw more SNSD pairings than them bonding with KARA. You can skip the first 2 mins btw:
This was from the end of Music Bank on the 19th last month when SNSD started performing RDR in those hideous white costumes and KBS once again messed up the results with Kara and T-ara.
The first time I saw this at that time, I only spoted TaeNy in the far back, HyoRi near that platform goofing off, Seohyun's impromtu Lupin dance followed by Sica fixing her collar (SeoSica?), and then a few of the girls (Yuri, Hyoyeon, Yoona, Seohyun, and Sooyoung) staying behind during KARA's encore.
Watching it again several times I noticed a lot more. There's Sunny standing slightly behind Hyomin and eventually laid her chin on her shoulder, a brief Shikshin duo momment where Sooyoung hugs Yoona from behind, Yuri hugging Hara, TaeNy walking off together, Seohyun surprising Jiyoung (you can actually hear her shriek) followed by a hug, and Sooyoung attempting to dance along with KARA before finally walking away. I bet Nicole and Gyuri were like
"What the hell are you still doing here? Get off the stage!" 
Somebody tell me who Gyuri was hugging and who was hugging her from behind, making a nice Gyuri sandwich.
