Maybe! Laurent tends to be very focused so he's probably a workaholic and preoccupied by making sure his brother is doing well, so if Severin came he'd probably feel a little third-wheely yknow. Laurent would try to be polite about it but it might be in that 'I WISH I COULD JUST STAY HERE AND INTERVIEW MY BROTHER FOR 12 HOURS ON EVERYTHING' way HAHA.
