Star Trek Discovery Episode 3.07 “Unification 3”
Burnham believes she can find the source of the Burn with more data. She wants access to Federation project SB-19, a possible space travel alternative to dilithium developed by the unified Vulcan and Romulan people on Ni’Var.
They believe SB-19 caused the Burn and do not want to give the data to the Federation, who they have left. Vance believes Burnham can convince them otherwise since her brother Spock began the process of unifying the Vulcans and Romulans.
This feels like a one room episode, where money is saved on CGI and sets by substituting it with a lot of talk. And there is a lot. Everyone is acting to the maximum and it all feels like a lot of filler.
