Ino knew Shizune could be a liability to her plans, and decided to do something about it. In the midst of the party going on, she was able to capitalize on a suitable distraction.

"Shizune, look! Tsunade's going nuts again!" Ino screamed.

"What!? Where!?" Shizune turned her back on Ino, trying to locate a possibly drunk Tsunade.

Ino then proceeded to knock her out with a chop to the neck and hurried away out of the party with a motionless Shizune, thinking she was also drunk.

- LATER -

Shizune was tied up, groggy, tired, and dizzy. She had no idea where she is, but the first thing she saw was a pair of sandaled feet that belonged to a stinky-footed Ino.
