It’s a shame that Regina is so blinded by her hatred for the Charming Family and her love for Henry, that she is desperate enough to tell Henry that she wants to be with him at the cost of his family’s lives. She clearly hasn’t learned a thing. She can’t force Henry to love her, especially when she believes killing them will fix everything. If that ever happened, Henry would just run away from her.
I’m glad Emma is suspicious of Tamara now, but she is in quite a dilemma. Accusing Tamara with not enough evidence will make it look like she’s just trying to make Tamara look bad at the expense of getting back together with Neal. Hopefully more evidence against Tamara piles up soon.
