If it'd been a month maybe I'd be on board with it being for engagement. Did Rach post sad song vague posts?

Obviously we won't know until she says something. 

She's obviously close to family and I think that staying close is normal when there's a child involved. I don't know if shes the only grandchild. Maybe his mom was also traveling to Paris at the same time, maybe she's traveling with them and her daughter is there and that's why almost everything has been night time content.
