Can anyone please confirm the following about Phasing? It came up in a game with a friend recently, and I'm hoping I answered correctly. For all questions, the situation is as follows: on an indoor map a character with phasing (P) and another character (X) are in adjacent squares, although there is a wall between them.

1. P cannot attack X with close combat
2. X does not need to roll breakaway if moving away from P

Insight appreciated...

If there is a wall betwen them, they are not adjacent at all, and the phaser cannot attack through a wall at all
