Thanks for the casting news
I'm on the fence with how I'm seeing this character go...
1. She is possibly secretly working for Hiram Lodge in some capacity
2. Maybe she an FP have a thing which, considering Jug wants his family back together, won't sit well with him.
3. After all the creepiness of Archie/Grundy I'm freaked that she might be another creeper and go for Jughead since he's looking to be a Serpent now.
