Do you have to play an event card if it's one of the two (or five) cards from which you select a different card during the Councillor phase? If so, do you then draw another card (or cards) before selecting which card you want to bring into your hand?
The rules are a bit ambiguous here, because technically you could pass over an event card, and thus would never have an event card in your hand, by choosing to discard the event card rather than taking it. On the other hand, this event card is "seen."
Putting the event card on the table doesn't mean it's ever going to be chosen by someone. And even if you thought the event you picked up would hurt you the most if someone did activate it later, conditions in the game could change and you might be the person wanting to activate it.
