| “ | You’re going to merge with me. | ” |
The relationship between two witches brothers Malachai and Lucas Parker.
It was revealed in Fade Into You that they were born in Portland, Oregon, in the 1970's, as a pair of twins for the Gemini Coven. Different from the rest of his family, Kai was born with no magical power of his own but was gifted with the ability to absorb the power of others. Based on the tradition of the coven, only a set of twins would become leaders, hence their name "Gemini."
On the other hand, at the age of 22, the twins have to merge power. The stronger one would absorb the power of the weaker, who would die as the result. Realizing Kai's disability, the Parker family kept having children until another set of twins were born. Luke and his sister Liv entered their lives as the 7th and 8th children of the family and the 2nd set of twins.

Kai killed 4 out of 7 of his siblings, attempted to murder the twins, but failed because Jo protected them.

In Christmas Through Your Eyes, Kai is seen at the cemetery with Luke and Liv.

Luke intervenes, trying to stop his brother after he stabs Jo again. Kai then shoves Luke into a wall and reminds him that he wanted to kill him when his brain was the size of an acorn and he doesn't have a problem doing it now. Luke shoves Kai away from him and walks out, saying he will not watch the current events unfold. Kai laughs after he leaves, shoving more signs of sociopathy in his eyes calling Luke "dramatic", much to Liv's visible annoyance.
In Prayer For the Dying Luke intervenes in the Merge between Kai and Jo, and offers to merge with Kai instead. Due to the fact that his imprisonment had kept Kai at the age of 22 and that they were of the same bloodline, it provided the needed loophole to allow them to attempt the Merge. Luke dies during the Merge and Kai now has permanent magic.
