I vote for Poinsetta; mine get all rangy and wonky after a few months outside, if they live that long. I've also seen them growing wild/escaped south of here. There are so many varieties, no telling what after they don't get the specialized greenhouse care.
You are right about the thing that when you watch only one image then it seems as that one looks like the flower is painted on the leaves. I also thing that the second plant image that may be the brother branch of the same seed which is looks as same as twins. So there is no doubt about the pant that both are same.
