It occurred to me that we haven't seen much of what Ellen can actually do beyond V5 and her clone spell in spite of her presumably having even more innate magic power than Elliot and an eagerness to use it.
The heck of it, however, is that it makes sense we haven't seen many of her spells. Functionally, they're almost all transformation beams, and many of them just have to do with different varieties of female form transformations. She's had very little reason to show them off in a proper story, and that's unlikely to change. New spells, certainly, but most of it is stuff that's just not going to naturally get used.
So let's toss pretense out the window and have this be what it is: A demonstration of a bunch of the spells Ellen has gotten.
And let's toss even more pretense out the window by admitting that, yes, I probably would have thought of a convoluted storyline with some excuse to demonstrate her spells if this was less last minute. Really, though, it's probably for the better this way.
