I really just did not like her. She was deceptive, a killer, and a liar. All these "good" protector people are "all the same," meaning she, Jacob, and MIB all manipulate and exploit people for their own agenda. MIB had justifiable reasons for making his decisions. She apparently burned down an entire village of friend/humans MIB had. Why didn't she do it sooner? Why wait until they discovered something. She knew where they were digging, etc. So she stole these 2 babies because she was lonely and then kills one because he doesn't follow her around like a puppy dog. This is just my little rant and don't know if it'll effect the ending of the show. Though, she's kinda like Eloise. She kills her son for "The Island."
