I feel like we're seeing more of the Leelo behind the curtain lately. Still a lot of random aggression, both self-stimulatory and calculated for reactions, which sucks for everyone including him. But he has been reaching out and interacting with us, and is using so much more language than we've seen in weeks or maybe even months.
Leelo sat in the corner of Iz's room and played (in a stimmy way, but still) with blocks for a good fifteen minutes tonight, engaging me to participate halfway through, imitating my two-block structures, encouraging me to imitate his, saying "Good! Great" when I "did it right," and encouraging me, "Come on, you can do it!" and "Yay!" when I completed my task. It was wonderful.
