What cruel cruel parents they are, playing with their children's emotions like that - lying to them until it suited Creepy (and the vlog) to do the big reveal on camera. The older two surely would've thought that something was wrong with Mum or baby, being strung along like that. Esme's initial reaction was definitely pure relief, on hearing the news that all was well and he'd arrived safely after all. Issy would've sussed what had happened but played along for the sake of the others but her tears looked to be a genuine reaction to Esme's sobbing, seeing her sister so emotional. And Isla just cried because the others did. What nasty manipulative pieces of work they are, making their kids perform in that way, demanding raw emotions on cue. And Granny too. What a witch.
For me that was a new low.
Oh and his constant compulsion to mention the blond hair...either way, blond or red, his obsession is going to negatively affect Esme (even more). Personally me thinks the d-head protests too much.
