Hmmm, thinking it through the ones related to each other just happened to have a lot in common (because of their related status obviously) so that would make the pairs be based upon the similarities the two may share somehow. And Ryan doesn't have to be the odd man out, we just need to find the most individual character out of them all and choose him as the one related to Miss D.
