Yeah, and Clem couldn't explain because she didn't know HOW. She was dealing with a shit ton of stuff, hormones on top of trauma, and it was never personal, she wanted her mom around, she just needed all the support she could get, and the pack also offered that. The two sides thing is perfect.
Probably will be, yes. Because Clem loves her sister, though she might not understand why she's close with their mom. Clem tried really hard to keep in touch with Pepper, and when they fell out of touch, she did go looking (which got her in a world of trouble). She does approve of the gun though. She'll teach Pepper all sorts of things she knows.
So once she gets past the gates (she'll have to have a reason to get in, probably), There's the bar with the open kitchen (I suppose I should name it... The Spotted Dog is tempting because it was Evie's baby). So she could run into Evie there (Evie is a friend of Clem) or you could talk with JS and have Linc there or Clem could show up. Or even Ty (who is her SO/mate, which might shock her mom!)! Ty belongs to Amy.
The first meeting might not go great, except for her being absolutely ecstatic to see her sister again. I sense a lot of yelling and cursing! lol. (Clem and cursing... yeah never expect her not to lol)
