When Brett decided to propose to Max, he came up with one of the most cutest and geekiest ways in the world to do it.
Both lovers of Pokémon, he decided to offer him a ring of his choice; a grass type, a fire type and a water type.
The grass type ring had a wooden inlay, the fire type was black with a red gem, and the water type had a mother of pearl inlay.
He said yes. Max picked the fire ring, but still got to keep the other two rings.
"At the beginning of every adventure, you need to pick a partner. I chose him. So, I figured if he said yes, he could decide what to wear on his finger. Whatever he picked as his official starter will “evolve” at milestone anniversaries. I got plans."
