The Tataridamashi manga adaption has been like that most noticeably in that...

Spoiler:

Rika acts a bit more like she's been through this same exact scenario before. But the way it frames Satoko makes it look like she might have been having second thoughts about her master plan. If I were to wager a guess, I wonder if she might have felt like stopping, but Eua (somehow?) put a stop to that (There's a hint in the anime to this effect. (Listen carefully to the scene were Teppei? attacks Keiichi.)) and basically forced Satoko's hand (Hence why Nekodamashi is as brutal as it is.)

Bonus: In the Watadamashi manga, Keiichi never breaks down the barred cell.
