Relationship between Grog and Pike

Grog Strongjaw and Pike Shorthalt became very close friends after Grog saved Wilhand Trickfoot's life, who happened to be Pike's great-great-grandfather, followed by Pike saving Grog's life when his herd beat him nearly to death for showing mercy. They lived together in Westruun from then until joining the adventuring party that became Vox Machina.

Pike thinks of Grog as a brother.
