TBH I don't know if there are new endings and I don't really know what triggered a different ending to show up. There was one thing I noticed though, which I'll explain in a bit. The ending you're talking about, the child eating one, was the second ending I achieved. The first ending I got from him was one where he killed me in a ballroom, in a substantially less graphic and terrifying away. Or at least I think it was a ballroom (sorry it's been a while). The first ending I achieved just by following the guides. But ya know how on the last day he asks you to meet him somewhere later? Well at the end of the day that scene where I go to the place to meet him didn't happen. I just suddenly showed up at a ballroom (I think) where he was, he flirted with me, revealed his evilness, and then killed me. After he killed me and I somehow survived the next day I just played the day normally. But this time the scene where I go meet up with him did trigger. Which is the scene that you were referencing.
