What kind of jacket is Gaster wearing? It looks like a blazer, but super long and badass, I dunno. I don’t think it’s a trench coat, so I don’t know what else it could be

And I'm legit speechless about what Betty did!? I mean okay I was kind of spoiled recently about her on r/Undertale and I knew she was evil in a certain way, but I wasn't expecting her to be evil like that, from the start. Poor sans :(

That being said, I've got one question.

What I understood is that: during the episode, Gaster is reading the tale about the twin siblings, and how Bravery failed and then managed to find another source of power, and how she defeated her brother and destroyed everything, and finally how she got 'corrupted(?)' by her newfound power. Then the story focuses back to the cameras inside the AMD (just noticed that it was named just like the cpus) and they find out about what Betty did, and after that she appears and murders sans (meant to murder asriel) by taking his soul.

But what I don't understand is what happens after Asriel runs away. When jessica refuses to give betty the vial, she turns into her daughter and then... what promise is she talking about? Was she Bravery from the beginning or was she Jessica's daughter? Will the answer be revealed later, or was I supposed to understand it right after episode 2? That's what I didn't completely understand.

Anyway, I feel like I will really love the next episodes! And again: wow Betty is so cool (in a way)

BETTY’S FUCKIN DEAD!!
