Bonnie had a very interesting storyline and development in yesterday’s episode: She finally realizes how much damage she can do with all her knowledge.
It started off with her saying after seeing that picture, “She drinks vodka, not scotch. Anyone close to her knows that.” It reveals she instantly knows the picture was a set-up. Yet, she is not aware of the fact how much of weapon such knowledge like this can be. She plays it down for now.
But then, Connor comes along and says, “But now that I have you here, do you have any AK tips? Since I’m the new you.” That’s the moment she realizes she has been replaced, no longer needed, for good.
That moment also triggers another realization. She understands how she can use her knowledge of Annalise against her. Not the big stuff of murderers, but the little stuff. All the details she has gained over the years of working with her.
She has no other option than to seek that other lawyer out and finally use the knowledge. If she wants to hurt Annalise, as she claims, this is the way. Boonie recognizes the power of her knowledge when she said, “I used to work for Annalise. I know how you can beat her.”
