In a few days Expect someone from CBS to be like oh no nah it's not happening, different networks, legal stuff, etc.
Unlike the previous president, this guy has a long history on working with The CW. He was responsible for the CBS television development, including the stuff they sold to The CW like Jane. He is also someone from 'development' unlike Tassler who was more traditional executive, so I hope he is more liekly to listen to Berlanti if he wants a crossover.
