Lol Megan doesn't really know Ella. And I'm not going to lie, I'd probably act the same way if I saw someone make a move on someone I liked. Lol except I wouldn't be so mean about it. No we won't be killing Megan :), just seriously hurt her.
Lol Megan is meant to stir up anger within the readers. I'm definitely bringing in the rest of the Penguins, but not until the sequel. Careless is just between Sid and Ella, but when I do bring in everyone else, I'll let you know!
