The large bloom isn’t really the best ending, it just means you got one of the furthest out endings, all the endings are valid in our eyes! It would tell you which is the key choice for getting other endings in the guide above.
Just got Jessie's alternate ending and I prefer it, because it allows Jessie to live her dream without having to hide her lupine self. However, in either ending, does Malcolm actually return? It said "Malcolm will return" (or be back), so I assume that means he'll be able to share in their lupine love once again. I didn't see that in the second ending, but I may have missed it (I skipped over the lengthy credit scroll).
Also discovered, Alana is a child of the fae as well! She be hoofin' it as well! There is definitely a fae connection between Alana and Effie. I don't think that was a visual mis-glance Malcolm saw in the back of the car. But those one-liners between chapters (and at the end) are so sad!
