Few things here:
Lack if interest in Fake's chocolate bars from Freddie, resumes his game, bars left on floor.
Odd way for Fakey to talk to a 9 year old "Yeah baby."
Fakey immediately focuses on NikNak. While NikNak spills the beans (you can clearly see him pointing to where he's just come from & what he's seen) Freddie is not looking up at all or laughing at NikNak's supposed made up tale.
Is she pissed off because he didn't make any effort for their actual wedding anniversary? Perhaps she did get him something & tightarse just brought his sweat home from the gym.
Plus I just listened again, something has happened as Fake says did mummy take all daddy's drink & NikNak said yes. So something did happen in front of Maris as he said yes. Right at the end he says something about - daddy happy. I think he's repeating what he heard daddy say or shout about being happy.
