A young man of Argelius II betrothed to the dancer Kara, whose jealousy makes him a suspect when she is murdered in 2267 after leaving a cafe with Scott.
Morla appears in the second-season episode Wolf in the Fold. Jealousy is considered shameful among the pleasure-loving Argelians, and he is plainly embarrassed by his own. He storms out of the cafe when Kara goes to sit with the Enterprise officers.
After Kara is found stabbed in the fog, with Scott standing over her holding the knife, Morla admits that he was angry and walked the streets alone. He has no witness.
He attends the ceremony at which the prefect's wife, Sybo, tries to sense the truth and is killed in the dark. He is then taken aboard the Enterprise for the hearing, where the computer clears both him and Scott by identifying the entity Redjac. Morla was played by Charles Dierkop.
