"Jake the Dad" was a good episode. It was nice to see how Jake would handle having serious responsibilty. I also like how Finn and BMO handled Jake moving out so well.
However, the ending felt a bit... lackluster. The fact that Jake and Lady's kids grew up so fast and can now take care of themselves feels like some way to make sure Jake could get back to adventuring with Finn. I say this because I felt as if Jake's kids would end up being more important to future storylines, kinda like how when Finn met Flame Princess, he started to crush on her instead of Princess Bubblegum from that point in the series. Jake's kids just feel like run-of-the-mill side characters at the end of the episode and let's face it, 90% of side characters in this show play a major role usually only one time and if they appear again, it's usually for some cameo or background role. Heck, we consider Lady Rainicorn to be a main character and most of her appearances on this show have been cameos and background roles. I mean, the writers built this moment up and I don't feel series got anything out of it in the long run.
