I'm not sure what discussion you mean, but the Winter War was, as the title says, in the winter 39-40. Finland and Germany only started fighting together against Soviets in 41 (Continuation War). There wasn't really anything strange about that de facto alliance; Germany wanted to attack the Soviets, and Finland wanted back the land lost in the Winter War. Naturally they would cooperate.
