Question about Power lost and Prisoner's passive

[fred10141988]

I have three questions.

1. How come sometimes when I didn't get first in PVP, my power was still only 3?
My opponent didn't have any toons could steal power.





2. Is there any bug in Prisoner's passive?
It should blocks all toons' passive of my opponent in first round.
But sometimes it didn't.





3. In my experience, if you killed some toon, the debuff it deployed will disappeared.
Am I right? Or actually that's also a bug?
Because in very few cases, when I killed toon, the deuff didn't dissapeared.
