I can think of danny, and the twins. you'll argue that they weren't part of the pack, but how were they different to mason in that regard? Danny and the twins weren't pack.

In fact, during 3b, the twins were trying to get into Scott's pack, but they were never able to do so. Aiden died, and Ethan left.

Danny wasn't even connected to the pack. He was friends with Jackson, but Jackson was never in either pack (Derek's or Scott's). He was a Kanima-turned-Werewolf that went off to London some time before 3a.

Mason is friends with Liam, who is in Scott's pack because he is Scott's first Beta. Stiles told Liam to tell Mason about the supernatural, which he did, but Liam also brought Mason to a pack meeting (see: Dreamcatchers).

To be fair, Stiles chastised Liam for doing so, and both Liam and Stiles told Mason he wasn't part of the "inner circle," however, that's most likely changed after the events of 5b. They did include him in the "Escape from Eichen" plan, after all.
