Didn’t their son have some kind of a problem too?
Not sure offhand about Jeb’s son. However, when you look at the two parents, what is the most striking thing is how different the two are in height. Jeb is tall, 6ft, 4, like his dad, while Columba is at most 5ft. even, when standing very straight. Good for them, that they found a soulmate. Sometimes opposites attract.
