Huh...see to me that's totally justifiable. Marco was right, he did deserve that punch.

It's not like she's trying to kill him, she just got angry for being betrayed and punched him.

I get why Marco did what he did and I'm sure Snow does too, but he did betray her and the lie ended up separating her and her daughter. That's really painful.

I don't think this is a sign of her turning evil, but of her becoming more realistic. At Paley, Ginny said that Snow would develop a more evolved way of thinking when it comes to protecting her family. That doesn't sound negative to me.

But I could see David asking where is his pure as white innocent Snow. If anything I could see this maybe causing a problem for them.
