Malik’s birthday

I’m back!! The thought just came to me, I don’t know if you’ll remember. But in Masterminds, the main reason why they rushed the escape plan was because they were planning to ‘weed out Malik’ before his 14th birthday. Did you ever think that while they were on the run, Malik’s birthday had passed? 

Also, it says in the book that Malik and Eli’s birthdays are only a few days apart, meaning that the first 3 osiris kids would have been born within a relatively narrow window if the numbers suggest birth order?
