to settle is always sensible. it costs less and it prevents more intimate details to come out: Alice because more abuse would be revealed about her that impacts any attempt at getting some job, Ioan because more lies would come out that could damage his career (and also a long court case overshadows your career at some point regardless), the children (particulary Ella) because more of the abuse they did on Ioan would come out. I also think Ioan feared that Alice would put them through the trauma of being on the stand like she recklessly did last year. And I also think he has realized that nothing will change if he keeps fighting but rather things will get worse because Alice will act out worse. Also in custody court decisions are always bad because they randomly decide something that usually suits neither party. I obviously dont know their settlement, how much each party got what they want, which compromises were made, which deals were agreed etc. but I simply cant imagine that Alice suddenly decided he is fine to be a father again, it will likely be Ioan deciding that its time to let them deal with their mess on their own. I hope he didnt give them too much money. he clearly had leverage in that regard. And it would be a parental failure from his side to reward them for blackmail/abuse.
