I’m also a little confused about the pack dynamics. I understand that Elspeth is Jake’s top priority, but shouldn’t he be concerned about his pack too? It seems like now that he’s out of the car he might want to “check in” with them.
Within a pack, telepathy is involuntary. It is currently inconvenient for the Volturi to find Jacob, Elspeth, and Addy (since Demetri is away tracking down Allirea and has his phone off, and Alice can’t see them). If Jake phases, and accidentally thinks of the fact that he’s in Wexford, Ireland, and he still has packmates who haven’t already been moved to Rachel or Becky’s packs, then the Volturi will get a report on the group’s location.

Aha—gotcha!
