How did his Vader go before mine?

Ah, I thought Traya's passive only works on non-TM related debuf lifting, but it seems I misunderstand how stun works. Just to confirm the mechanic behind "stun", does the stunned hero still wait for his turn as usual, once his turn is up, the game just toss a "no action" and move on to whoever is next in line? and if Traya is present, then lifting the stun means user can now issue action on the hero as if he has not been stunned?
