Invade Your Territory:Â Namor ignores Barrier and Smoke Cloud markers for movement purposes and removes them from the game when moving through them.
 ...And Leave Behind a Bit of Mine: When Namor or another friendly character uses the "Invade Your Territory" trait, after actions resolve, you may place a water terrain marker in any of the squares from which a Barrier or Smoke Cloud marker was removed.
1. When Namor moves through the markers, are they removed as soon as he moves through them or after his movement ends?
2. Do Namor's water terrain markers ever leave the map?
