Honor of a lion

Some spells look at the honor of the target to determine effect. For example, Water 2 has a healing spell that only heals Honor 4.0 and up, while harming any tainted person.

Now, what the spell does to a Matsu Beastmaster is known: his honor rank rules that. But what about his trusty lion companion? Does he get his own honor rank or uses the one of his master or none at all?
