When I made the original Your Last Friend, I never in a million years expected it to get over 150 thousand views. I barely expected it to get 2,000. As such, I did not put a lot of effort into it. I tried, obviously, but I didn't give it my all because "no one's going to watch this anyways, who really cares?" As it turned out, a lot of people cared. And thankfully, my subpar effort was enough for people. But it wasn't for me. This song has been gnawing away at me since I created it. To put it short, I wasn't satisfied. So, before it likely becomes my most viewed video, I decided to come back to it and fix what I thought was wrong. I don't think there will be a V3. Not unless future me becomes unsatisfied again. But, only time will tell there.

Thank you all for the support on the original video. The amount of love it's gotten has truly blown me away. As I'm finding out, my most popular videos are things I could never anticipate.

Copy and pasted explanation of the concept from the original description:
"The concept I've had for this fight for a while now is... well, it ties into this whole AU I've been making. But, if we cut it out and just throw this concept into Undertale itself, I'd say it works pretty well.

Basically, for this fight to happen, you'd had to complete a True Pacifist Route, then reset and do a Genocide route. But, for some reason, Flowey actually remembers what happened on the Pacifist route, and finds himself very angry at you for both resetting, and (eventually) killing everyone he very temporarily liked. He doesn't help you like he normally does, and at the end, just after killing Asgore, Flowey will fight you, which is where this music would be played. He knows he'll lose, but he doesn't really care. He survives your attacks by ducking into the ground, similar to how Sans dodges you.

All very rough draft stuff, but I thought it was cool enough that I had to make an actual theme for it. And, I thought I did well enough to actually post it."

Everything is by me, but I did heavily reference a sprite I found on Google for Flowey. When I click on the link, however, I get an error 404 page, so I do not know who made the reference.
