What episode of 6teen does jonesy say Nikki is the one?

Jonesy never explicitly says Nikki is "the one" in any episode of 6teen. He does, however, express strong feelings for her throughout the series. Here are a few examples:

* "Jonesy's Girl": Jonesy is very protective of Nikki and gets jealous when another guy flirts with her. He ultimately reveals his feelings by giving her a hand-made necklace.

* "Best Friend": Jonesy is initially upset that Nikki has a crush on a different guy, but he ultimately accepts it and remains supportive of her.

* "The Date": Jonesy is incredibly nervous and sweet while on a date with Nikki.

While Jonesy never uses the exact phrase "the one," his actions and words throughout the series clearly show that he has strong feelings for Nikki and sees a future with her.
