Yay! William the 30 yr old BOY has gone home!
Did people see how immature he is? From ratting out Ben C, to the fact that later, he just assumed things were fine and he was getting a rose, to actually admitting he DOESN'T WANT TO GROW UP.

The immaturity and lack of depth was just so evident in his eyes.

He was basically CLUELESS until Ashley told him she just doesn't feel it for him anymore. He was so full of himself, he lacked the depth & empathy to understand where she was at.
And in the end, in the limo ride, all he could think of was how he'd go back home to nothing.
That was more important than WHO Ashley was and whether they were compatible.
THAT is why he threw her under the bus at the roast. His eyes were fixed on the fortune & fame of being a comedian so he could get out of that hole.
He was more concerned about not wanting to crawl back into the dark hole that HE created into his life.
(Can you tell I have a bug about boy/men?
