Yeah, true. Her impulsivity was still noticeable in S7, and to a lesser extent S8 (To Change A Changeling is a good example, since it got mentioned, with her shitty plan that kinda fell apart. I think I’ll end up rewatching it, now that it got brought up), I’m talking more along the lines of her being say, comically, exaggeratedly amoral with mind control, when S7’s premiere had basically said she was done with that one (heck, Trixie suggested it basically, whether it was to be interpreted as joking or not),
and no, I don’t count consensual hypnosis as having equivalence.
And that episode was well-balanced between those two, wasn’t it?
(Definitely wasn’t a hard line for “here, Starlight’s definitely a good pony, for sure comparable to one of the Mane Six,” although that line was probably passed by S9, by most accounts)
