#It's just Tina trying to get JJ interested in whatever she's doing by being vague

[dreamboundedstar]

Well narratively speaking it was to make the easy innuendo. In terms of character, Tina was probably instructed by Louise to get Zeke because they needed a "hammer" for the whack-a-toe while Louise and Gene gathered the others during recess to speed the process. Tina kept it brief with JJ because she would take any skill he could bring to the team just so she could be with him, even though she wasn't asked to add him. It's the Belchies all over again! She also probably kept it vague for JJ so he would be curious enough to follow her and see what the heck is going on. Still, it is adorable to see Zeke getting so enthusiastic about the prospect of winning a dune buggy.

By rewatching S9e2 I noticed (along with before) that Tina only informed Zeke about the plan and he automatically agreed to help. Though Zeke is always a helper to others but bit more so with Tina. And what really gets me is that she explained it to Zeke but not Jjr. I don't know how to take it but it's definitely a different level. Because she would always try to include Jjr first on things and doing the opposite with others by trying to ignore mostly. Probably just looking into this too much but I'm really intrigued by this.
