Added more commentaries (which I couldn't make sense of, unfortunately)... and one Twitter reply noted something interesting about the policewoman's outfit.
That's fine, but first I think you should catch the man behind you.
... Did he just poke fun at the real-life illegality of Onii-san being in a sexual relationship with Ai-chan and that only Onii-san would face any legal reprecussions from that?
Actually M950A is angry that Thunder cheated on her with Scarecrow and had a daughter, SAF, which a guilty Thunder tries to hang herself.
This is based on a joke by the fandom that SAF is Thunder and Scarecrow's daughter, like how they joked PA-15 is M950A and Thunder's daughter.
Wait, wasn't the opposite?: SAF looks more like a Calico and Scarecrow's daughter rather than Thunder and SC's. The 'cat ears' thingy and the shades of aqua-color hair gives a 'M950A vibe'. I genuinely thought Thunder was about to hang, or at least tie, the randy beast that Calico must be.
