Jurassic World Dominion: 10 Original Trilogy Characters We Hope Will Return

Speaking of the unbearable Kirby family, there was only one person on the island that was able to keep Dr. Alan Grant sane: Billy Brennan. A colleague of Dr. Grant's, it was evident that the two had a close friendship that showed shades of a familial bond. In many ways, Grant was mentoring Brennan as if he were an older brother or even a fatherly figure.

Young, goodhearted, and a little naive, Brennan was a little too much the younger Alan Grant, which ultimately created a fracture in their relationship. Apart from learning that Billy was alive and Grant was relieved, we have no indication on where their relationship stands post-Jurassic Park III.

Billy was a bright spot in Jurassic Park III and his relationship with Grant, personally and ideologically, deserves further exploration with Dominion's coming events. Will the two have mended fences or has Jurassic World created a deeper rift in their relationship?
