Really? Lydia is going to have a cow, if she finds out that Derek is talking about her switching packs. I am curious how that is going to develop. I hope Stiles is present when they talk to Lydia about it, because I want to know what happens.

True, Derek has never been a part of a pack as an adult, though he did grew up in the culture. We can't discount that. I am still giggling about Derek being considered hospitable.
