Ok I found the issue, apparently that cutscene also triggers if you didn't spare berdly in cyber city

I've been replaying both chapters of deltarune lately, but when I was on the queen fight on my file where I aborted snowgrave to get the thorn ring, I didn't damage queen at all, only the acid barrier, and loosened berdly to 100%, however, it still gave me the cutscene for when you beat queen with violence, I tried it again and got the same result, for clarification I group loosened every turn when the acid barrier wasn't up, and when it was, I destroyed it first turn every time, the first with everybody fighting and the rest with a red buster and ralsei attacking.
