I have been off air for almost 24 hours and I see no-one has waited for me
I reckon this trip to Wales covers a few bases.
His anxiety needed cooling down so visit with the family. Bonding between Mama G and Bianca. Maybe rebuild bridges with Alice's father.
He prob doesn't want to be on the same continent for the RO hearing.
Might be scouting for work, might even be scouting for a new home. I know he says he loves LA and the girls are US citizens but the last 6 months might have changed his mind. Bianca will prob happily move wherever and if the movie industry is going ahead in UK, why not make their Ray of Sunshine there? Leave Alice in LA. He can always pay for her to travel over for short visits to see the girls. Cost/benefit ratio would be better doing that any alternative.
