I think Philippe IV living longer will have huge effects on the whole succession’s debacle...
First his sons will be likely divorced by their unfaithful wives earlier and so remarried earlier and is possible who also the wedding between Philip (V) and Joan will be dissolved here and he remarried to another princess... Butterflies can easily altering the deaths of Louis and his son by Clementia (who likely will be called Philip and not John here)
If Philippe's boys are separated and remarried earlier, would these boys still marry the same brides as OTL? Or might the boys get different brides because reasons?
