Hi Milkjon. Thank you for catching that error, which is a result of the translation software I used in translating the information I used to write the articles from Finnish to English. I have made the correction, both in Lassi’s profile and on the “Michael” cast chart in the BETM Cast Information article for the Finnish production of the show.
