OMG today episode was just so :lmao: I feel really bad for Nan. First she found out that Kat and her don't share the same mother and then now they don't share the same father but it wouldn't matter. They grew up like siblings so that makes them sister already but then again... lol so many buts... but I have an friend, who is the only child and has an adoptive sister and brother. She wished she had a blooded sister even though she is happy with her adoptive sister and brother. I guess when it comes down to it, you would just want a sibling that has the same blood as you.
