Krill

After the Orville confronts a Krill spaceship attacking a federated plant colony and captures a shuttle, admiral Ozawa orders to use it with an anatomic disguise devise to go undercover aboard the major ship. Captain Mercer and pilot Malloy must pretend to be sole survivors of a battle with humans, win Krill captain Haros's trust and get insight in the 'Krill Bible', the secret basis of their inflexible religion of Avis, which gives them a sense of divinely ordained superiority rendering peaceful coexistence with other species pointless. As if the suspicious ship 'chaplain' requesting a guard to the chapel weren't bad enough, the infiltrators discover a super-weapon aboard but get conscious issues about the Krill school children and their teacher to Ed's taste, Teleya. —KGF Vissers
