well if thats the case, james and lily were pretty young to have a baby 😑 thats 3 years after they left school... they started going out in their 7th year... supposing they got married a year or so after they left school... its possible i know, it just seems really young to be married and already have a baby... but there doesnt seem to be any flaws in your adding up the years and stuff... ok this message is getting slightly pointless, i think i'll stop now.
