[Marvel] What would happen if The Vision and Shadowcat try to phase through each other?

usually when Shadowcat phases through machines they short out so  with vision what would happen?

Whatever Vision wanted.  He could phase at the same level as her, allowing them to high five but not pass through eachother.  He could do nothing and probably suffer some negative effects.  He could phase at any different level and both would pass through eachother just fine.

Shadow cat doesn't have anywhere near the level of fine control as Vision.  Her phasing is ON or OFF, more or less.  Vision can adjust it.
