Couple + Sibling/relative third wheel is honestly an S-tier trio dynamic and I wish we saw more of this in media.
"You are my soulmate. We are forged together by battle and tears and love. Also my brother's coming along."
"Yo."
Bonus points if the non-related half of the couple is just as committed to keeping the third wheel around as the related half.
"Isn't it weird that your brother in law is always hanging around?"
"You've got a problem with Andrew?"
