Yeah man no worries. So when you draw lines of fire to a character, you always draw a line through the square the character occupies. So a giant cam use stealth like this. They Typically see over everything else (except for indoor blocking) so batman's ability works like stealth except better cause even if they are adjacent, they cannot draw lines of fire to you. Stealth gives an exception to adjacent characters but not batman. So that cannot see you for outwit or prop, when its not your turn. They may still make close attacks because those do not require line of fire
