SOMETHING WHEN GONE, YOU CAN NEVER REGAIN: FREE: For the rest of the game, Batman can't use the Batman Ally team ability and whenever he occupies a clear square and is given a RANGE action to use Incapacitate, Mind Control, or Penetrating/Psychic Blast, he can use and may instead target all opposing characters within line of fire.

Part 10: Terrain
CLEAR SQUARES
A square that isn’t hindering or blocking for either movement or line of fire is called a clear square. Clear isn’t a type of terrain, but rather an absence of terrain

Part 11: Objects
HEAVY OBJECTS AND LINE OF FIRE
Objects placed on the map do not affect the terrain of the map or movement or line of fire in any way, with one exception. The exception is that when drawing a line of fire, an otherwise clear line of fire drawn through a square containing a heavy object becomes hindered
If Batman occupies a square with a heavy object, can he use Something When Gone, You Can Never Regain to target all opposing characters within line of fire?
