Mafia 110. Heckelia

Oh, you're getting confused, Tox.

Just in case, here's the order of night actions in my understanding:
0. Concert of Piony (displayed).
1. Preparation of Inar (not displayed)
2. Blocks Zhen Lo (displayed).
2.5. Blocks Shizuo as Shendet (displayed)
3. Blocks Shendet (displayed).
3.5. Blocks Shizuo as Dario (displayed)
4. Isolates Dario (displayed).

Besides Shizuo, there's also Shendet here.
Blocking by Ment with Shizuo and Shendet doesn't differ in any way - whether Ment doesn't move in one case or doesn't move in the other.
The question is, why, when blocked by Shizuo, Ment becomes peaceful, but when blocked by Shendet, he doesn't.
