With Kathy on hiatus, we welcome Tim Mitra as guest co-host this week. He is a mobile apps developer and producer of both a tech podcast and a scifi podcast. Of greatest interest to SestraCast? Tim lives in Toronto, practically next door to the Dyad Institute. We talk about the Canadian-ness of Orphan Black and its cast, and how the show was received in Canada. We also try to untangle ever more complicated genetic shenanigans.
