You know Lambchop, I was thinking about that too. After the foreman sent the note to JSS, J17 sent her note as well, and we don't know what she said. After JSS spoke to 2 of the 11 DP jurors, and J17, J17 started "particpating" (which could just mean she was going through the motions as a CYA).
IMHO, Jodi did feel abused by Travis in her warped perception of reality. Most of us see that she wasn't abused, but thankfully we don't think like her. Travis did not want to share his life with her, and leading up to his death, he started calling her out on her escalating intrusive behavior. She felt extremely threatened that Travis would expose the person she really is to the world, and her mind, killing him was justified.
What if J17 relates to that, as in she thinks the same way as Jodi? We're already hearing she feels attacked and assaulted, with no credible threats against her. She doesn't like people questioning her thought processes, or motivations, even though her posture and words while deliberating are suspicious. She wants to be a victim now, but IMO she is devious. It's all for naught now, but that's my opinion with what we know at present.
