Grace and Luka Relations

Description
Grace and Luka perhaps have the weakest relationship within the group. Grace only appears in the fifth book Bors and the Senior Scramble and Luka is only a prominent character in the first three books. They never have an on screen with each other and they're kind of just associated because of their friends. The two are rarely in the same room with one another and both leave when everybody else does.

History
They actually end up in the same friend group along with Mallory and Tomas in Bors and Before which takes place during their 6th grade year and actually hang out some in 7th grade as a part of their friend group which is a sort of proto-InTBH. Grace eventually drifts apart from the group and doesn't make a major return until the fifth book Bors and the Senior Scramble where they start becoming friends.
