Bones is inching ever closer to its 100th episode, which is set to air this Thursday night. And avid fans of the show are supposed to see a resolution to the possible romance between the lead characters Seeley Booth (David Boreanaz) and Temperance “Bones” Brennan (Emily Deschanel).

The relationship for the two has grown over the past five years and though we might see a bit of sexual tension, Deschanel insists it’s more about true friendship…a claim that hardly anyone watching the show buys into. After all, they’ve appeared to be hot for one another since the first season.

The 100th episode of Bones airs April 8th, 8:00 p.m. ET/PT on Fox.
