Renji n Rukia

I was just browsing <Bleach> comic..
When Ichigo dropped Rukia onto Renji in Book 18
why not they end up like this!-__-???
I know it doesn't fit into the emergent situation at that time..
But why that scene has to be so funny-_-!!!???
Don't know what's Tite Kubo thinking about.!
My poor Renji...

"you just come back like nothing happened after 3 month break!?"--I said to myself.
