They look very similar! I actually thought they were the same person as the families seating position was moved around for each interview. Both white, long blonde waved hair, conventionally pretty. Dylan's gf just a slightly older version.
In the photo posted, that's Paul's mum on the right of his girlfriend. She gave me real pick me vibes in the interview the other day. Excusing and minimising Paul's behaviour: 'he's having a laugh', 'i know he's been in arguments and little things like that', 'we're scousers, we love an argument', 'he's got a heart of gold, but we haven't seen it yet'.
