I've enjoyed Alex and Neil's partnership and although I'm sad to see them go, but she left on a high.
I also mentioned Alex and Neil's body language on ITT a few weeks ago and did you see them with Claudia after they were safe from the dance off last week? If Alex was uncomfortable with him being tactile, then I don't think she'd have no problem in letting him know.
They are clearly fond of each other, going by their social media but for some reason, I still don't think they're a couple.
