In full disclosure that was actually a part that had me stumped while writing. I was originally planning for him to initially go with Ingrid and following the argument with Blake the former was going to stay behind at the food court. Then Marcelle would talk her into handing Tanner over to her or Blake. At that point Marcelle would find a way to ditch Blake. But I figured there would be too much meandering for going so roundabout with it.  Per logic in story, Tanner's trying to keep on Marcelle's good side for whatever it's worth and he also thought it'd be fine since Ingrid and Blake were around to keep her in check.

The condescension towards Abigail was unintentional on there part, they think she's just in that 'finding herself' part of her life. Blake of course loves her very much but doesn't really get the core reasons for her sister's demeanor. While yes, some of it is a little bit embellished it's not entirely teenage angst like Blake believes it to be.

Thanks for the comment!
