Wolverine had, of course, noticed the mint condition '67 Impala in the parking lot. The monster expelled exhaust like a freight train, so he preferred to take the lead with his motorcycle, or ride along beside during the trip. Once he had considered it he had deciphered where the 'wendigo' was living. The voice on the phone, Wolverine presumed it was their father, had used a military code.
Wolverine didn't have a high opinion of the man, leaving his mutant sons high and dry in a decidedly anti-mutant society. Then again, yinandyang didn't need anything more.
Maybe SamandDean didn't either.
