Everybody needs good relatives..
So Summer and Andrew have gotten together in Neighbours. This is, obviously, illegal, since they’re totally related.
For starters, her step-mother’s mother is Andrew’s father’s ex-wife, making him her step-step-uncle.
Also, her father’s sister’s baby’s father’s son’s girlfriend’s mother’s husband’s late wife’s brother is Andrew’s father. Or, another way, Summer’s cousin’s half-brother is married to Andrew’s step-cousin.
Okay, so probably not illegal. I just like playing “join the dots” with absurdly interconnected relationships in Soaps…
