Ah, words? We shall have to see if Orion beats James to it. After all, the Potters are still a decent family even if they have let things slip, and he wouldn't be afraid of trying to talk both Sirius and James back to the light.
Orion is almost the opposite to Walburga in personality, but even so will defend her to the death. But that shouldn't be necessary at this point- still, James might find talking to Orion easier than trying to talk to Walburga.
