I am seriously questioning the healthiness of CS’s relationship within the show even beyond the usual stuff.
Hook getting jealous over Emma’s friendship with August is a bit of a red flag in my opinion. Emma shouldn’t have to justify herself to Hook over August. The fact that she feels she does implies that Hook doesn’t really trust her to be friends with a guy without something else going on. Then towards the end, it felt like Hook was giving his blessing/permission for Emma to be friends with August. Emma doesn’t need Hook’s consent to do anything least of all who she can/can’t be friends with. That just seemed a bit too controlling on Hook’s part for my liking.
