[the first person Leia reaches out to immediately after the confrontation with Anakin is Bail himself. Partially for some sort of comfort, if she's being honest, but largely because out of everyone, he's the one with the most pressing need to know. Since, after all, Anakin had threatened him. Repeatedly.
It's voice this time, not image, because Leia isn't sure she trusts herself to keep an even expression on her face. Even with her best efforts, the anger, hurt, and fear resulting from her encounter with Anakin pulse faintly in the background of her message. She's trying to keep it together, to not let on just how much she's actually bothered by all this, because it's not the time. Not when she has more pressing things to worry about first. Not when she expected this to happen eventually. She just didn't expect the threats to Bail that came along with it.]
Voice; after The Anakin Fiasco

Someone told Anakin.
