The memory of Mycroft is still difficult for them both, so Joan doesn't comment on it. Maybe at some point she'll tell Ted more about what happened. Of course it involved her own kidnapping, which Joan hasn't shared with Ted because she doesn't want to either trigger his trauma or make him think he needs to prioritize her experience.

Getting down on the ground is surprisingly difficult due to the lingering weakness in her muscles. Between Sherlock and Ted, though, she manages to get into a good position. Sherlock then sits as well, on the other side of the blanket from the two of them, giving them some space.
