Leave it to Portalocity to decide a five-hour layover in 18th-century Hawaii would really enliven Jack's attempt to rush from Beacon Hills back to Fandom. It wasn't as if he was trying to get help for a dying packmate or anything, after all.
Since he had to open the club anyhow, he went there went directly from the portal and left a
message for Stiles before tapping into the multiverse Internet to see if he could find anything about different types of wolfsbane. So far, all he had was a disturbing amount of Wendy the Werewolf Stalker fanfic in which Wendy cured Seraphim with -- things he was not about to do to Derek.
The Devil's Nest was (nominally) open, though Tiny was a better bet for service than Jack.
