We are playing the Tutorial and the Wookiee player has moved on to the terminal to block line of sight to it. First can a Hero or Imperial block line of sight to something that any figure can interact with ? Second if not how can a Hero or Imperial stop a figure from just moving up and using an action to interact. At this time the Stormtroopers are one space from the door in 07b, the wookiee is on the terminal in 38a and Fenn is in 33a. My Heroes do not want the game to end by the start of the second turn however the Imperial player after one of the Heroes goes can just by pass and use an action ending the game.
Can they stop this ?
