So just a quick little Question about companions.

Do they pay double movement to enter an enemy figures space.

Yes they do.

However, enemy figures don't pay double for a space occupied by a companion.

One extra movement point to enter a space with a hostile figure and one extra to enter a space with difficult terrain.

The companion rules only allow other figures to enter a space with a hostile companion without additional movement cost for the companion(s).

Thought so, just wanted to be sure I hadnt missed something
