Here's what I know about Jack and Dani from the show:
* Jack is not Dani's house crasher in the original series. He was a recurring character in the original "Tracy Beaker" series, but he was not involved in any house crash situations.
* Dani was not a main character in the original series. She was a character introduced in the spin-off series "The Story of Tracy Beaker."
Therefore, Jack is not out of Dani's house crash in the original series of "Tracy Beaker."
It's possible you are thinking of a different show or a different storyline within the "Tracy Beaker" universe. If you can provide more information, I may be able to help you further!
