So Today I was thinking about the various time gaps in vegebul's storyline, and I realized the 3-years-gap is probably the most over-analyzed bc it is so fascinating, but I guess it is still not my favorite gap.
3 years Gap: from Bulma flirting with Vegeta to basically baby Trunks
7 years Gap: from Vegeta not wanting to fight anymore (and spending the night with Bulma 100% canon before Future Trunks left) to Vegeta being a present father and husband (but still with some restlessness inside)
6 months Gap (?): from Vegeta's final atonement and Bulma forgiving him again to the MY BULMAAAAAAAAAA
1 year Gap: from the Zamasu arc where Vegeta and Bulma are the strongest pair ever to PRINCESS freaking BRA!!
I would say if I had to pick my favorite I'd probably choose the 1 year gap or the 7 years gap, but seriously it is very difficult to say.
