I will tell you just this:
*SPOILER*
...Mikko is a legit lunatic in that one and it ends with Arvo leaving for Anslo by bus after asking Dan when it comes by.
It's shitty to me that Mikko would act like that because it's legit something a luny would do.
Btw to get it you have to not move closer to him when on a walk while he's doin his music stuff.
