Gemma is missing her cat and the baby, she was not made to feel, but over the last few chapters she has somewhat developed a different personality from her initial cool, distant self, devout to studying only - and she has expressed a curiosity and desire to see the world outside.
She even has to justify her presence at Kane's doorstep with the fact that Circe kicked her out, when we know very well Circe is about people's freeling chosing to stay or go.
Eventually they go back home - lots of people asked "where is the baby", well you know they did not fly there hahaha Gemma has her own ship and crew so they probably left him to take his nap.
They cannot find the doctor at home because he is at Lio's, remember? She just broke her footsie, Foxy brought her a baby, the stork is calling his companion and then the kitty walks in.
And Papadopulos' bad habits never die.
While this is just a reminder, once again, that Colapesce calls Cosimo "little sister" and he calls her Unkel.
...so she makes a deal with them - using dice, remember? - and cheats.
Then Circe is all upset and says that witches don't forgive and don't forget - which is something she is struggling with as she supposedly should have a heart that cannot feel.
She becomes her lost child.
Apparently she is very good to children too.
He finds his half brother there - the man he cannot hug because he never hugged him as a kid.
We know from "Hugs" he doesn't like to be touched by him - but this is the story where he asked him to be a good father to Josh. We also know from Circe's teasing that he sang "hugs" and she poked fun at him.
Kane cannot hugs this guy because he cannot go for empty hugs. It's only that now he knows the reason why this hug is empty it's because of what he has done. He knows, it was all his fault.
He also has just read the final words his father left him on his journal, to be kind to those he meets because everybody is fighting a hard battle.
Does it really meatter? It doesn't. Kane can finally hug him, that's what matters!
The most important thing is that HIS curse is lifted and his curse had nothing to do with magic, it was a psychological block of sort, but now he is free.
That's all we need to know.
