Rules question about the guard

By hillep, in Masques

The rules state:

"When a player places a guard, he takes one guest card (faceup or facedown) from either of the two hallways closest to the guard and places it in any vacant hallway in the palace."
Will the guest card stay as it is (faceup stays faceup and facedown stays facedown) or does the facing change?

No change. The only card that puts a guest face-down is the assassin (by "killing" the guest).
