Point 1. - Not the breakdown she would be concerned with. Winter's image to the Accorded Nations because of the Lara/Harry pantomime, YES. Hence the marriage. She couldn't care less about Harry's feelings towards Murphy death.
Point 2. - Even Harry has poo poo this, Mab does NOT think this way.
Point 3. - Mab is always planning and none of it is going to involve caring about anybody's feelings, least of all two of her vassals who should get over it and do their jobs. A Harry/Lara pairing is indeed strong in more that "a bodyguard for Harry" way. BTW - A bodyguard for her bodyguard? Mab? Probably not.
Point 4. - Molly said that Sarissa showed Mab Frozen and it seems very unlikely that a political marriage (the norm in Mab's day) came from a Disney movie. Also remember Mab's feelings towards Disney, I'm more amazed that Mab actually watched the movie in the first place.
1. But remember, she was proud Harry had not given into the Winter Mantle like the last Knight she had to replace. And then Karen dies and he does give in to it. I think Mab has a vested interest in keeping Harry mentally and emotionally stable. Not because she necessarily feels about it, but because it's practical for her to care about her knight being effective.
2. Harry is an unreliable narrator who has done a 180 on his views before, and his grown and understanding about the world have already changed dramatically. Look how upset Mab gets when he crosses her will. She is concerned about the Winter/White Court relationship, so the Council continuing to rebuff her probably DOES PO her. IMO she wants everything she can get connected to Winter.
3. I think it's been established the fairy get some precognition as to when trouble is coming down the pipe. Mab is a schemer, so I see this as part of an upcoming scheme in which it's important to her agenda. And not just at the political level. I certainly get the impression she's planning more than meets the eye here.
4. Agreed, but I can see her thinking that Frozen is how mortals think about romance, which is just...so freaking wrong.
