It was right after an episode of Keeping Up was aired, showing that the pair were having issues in their relationship.
Shortly after, Kourtney had reactivated her account and re-followed Younes, however in that time, Scott had unfollowed his girlfriend Sofia.
It's been known ever since Scott and Kourtney's split that he wanted to get back with the mother of his children, even admitting how jealous he was of Younes. So did Scott see her IG activity as an opportunity to win her back? Probably.
Now, it looks like the damage has been permanantly done with Sofia, and she has unfollowed him.
Although she has kept photos of him on her Instagram, Scott has gone through and deleted a whole bunch of them together from when they were dating.
Will Kourtney and Scott somehow get back together after all this mess? Probably.
