I feel that Jade is missing her family and wants to be in familiar territory. The relationship bashing her and Ed have received whilst doing the Xmas task is taking its toll. Also trusting Tahan wanted to hang out with them and then to find her willingness to embrace once again thrown back at her. It is putting doubts in her mind and she is trying to cope.
I saw a heading but no video to match that she and Ed talked about their parents yesterday.
It's actually a pretty common way of psyching yourself up not to get something.
For instance with Ed she tells herself it probably won't work outside, for BB she says she probably won't win.
That way if something does happen that's great but if it doesn't at least you have that bit of protection upon your vulnerability that you didn't expect it anyway.
'Prepare for the worst, hope for the best'..
I seriously don't know why people find it so surprising.
