In this episode, Staz's brother got arrested in the beginning and a big plot got started since along with more problems. It's pretty cool and more randomness as usual.
Another nice addition is that they explain more on what's going on and show way more personality and goals on the characters. Also they revealed the kidnapper's actual identity along with his intentions on why he's doing those actions and gets surprising. Anyway, I do notice this series reveals mysterious characters and introduces basic info about them on every next episode and that's good since there are a lot of events going on. Other than that, the series is just getting better so far with more interesting plots that trigger one after another.
Conclusion: More interesting plots going on.
