Because I get pissed off when people think Flo is Charlie's mom (his mom looks different and has a different name. it's in Annabelle's book. -.-) and that she never had a thing going on with him. With all the differences between the first and the second, I simply believe they forgot about Flo, along with plenty of other important details. But, the two actors were together at the time but broke up. I dunno, but I liked Flo more than Sasha. This made me happy, yet sad. Come on, he looks so damn happy after she licks him. Also, these two just, wow, how they're near each other, how he acts like a father toward the pups (guys, THEY'RE ORPHANS. Not Flo's real pups.) and so on. IF YOU SHIP THIS.. YOU ARE CONSIDERED AWESOME.
