Time travel is always the best solution to deal with an unwanted pregnancy.
See that?! I linked “unwanted pregnancy” to the Braid comic I did and not this Portal comic. Classy.
Zelda is lying. It’s not Link’s kid at all. They actually need to do it first, and we all know she has turned him down every time.
See, when it comes to Mario, I’ve always interpreted “I’ll bake you a cake” as innuendo. Remember, these are games nominally for usage by children, so “WE SHALL BONE WILDLY” isn’t something you’re going to hear overtly. But I don’t recall Zelda ever having a “I’ll bake you a cake” style moment. So while normally these “the hero does so much yet never gets laid!” lines just annoy me, I guess for Zelda, maybe it makes sense.
ON THE OTHER HAND, each given Link only rescues each given Zelda once, so it’s a totally different dynamic. There’s lotsa links and lotsa Zeldas after all.
Actually, there are some Zelda games that are direct sequels to others, with the same Link and Zelda.
Admittedly, the only set I can think of off the top of my head is Windwaker and Phantom Hourglass, but the point stands.
The only character who has ever expressed interest is Ruto, and Nobooru if you want to stretch it.
