Tomás was the dashing heir to the Portuguese throne since his fathers petition to declare him legitimate (he is the bastard and only son of the Portuguese king).
Tomás was born in Portugal as the illegitimate and only son of the Portuguese King. He told Mary that he married his first wife because of love and then she later dies of influenza. It was revealed that he murdered his first wife.
In the episode Kissed, Greer mentions to her friends (Mary, Aylee, Kenna and Lola) that Tomás, a Portuguese emissary and illegitimate son of that country's king, has arrived at the court in order to negotiate a business deal on French timber exports to Portugal. Excited, she shares that she is expecting a marriage proposal from him. Later, Greer appears with Tomás when they encounter Mary, who has climbed a tree to retrieve Prince Charles' ball. Tomás is immediately intrigued with her at the sight of a tree-climbing royal.
Tomás invites Mary to go riding with him. The two ride to an old church that was originally built for King Louis VII. Once there, he presents her with a coffer full of treasure and asks her if a gift of it would cause a woman to think kindly of him, to which Mary says yes. Tomás then takes a ring, and, descending to one knee in front of her, offers her marriage, somewhat to her surprise. Tomás reveals that he cannot take his eyes from her, and is enthralled by her free spirit as a person. To persuade her, he expresses sympathy for with her dependency on the French alliance to support her kingdom's security, and also that she has had to go about this task single-handedly. He also guarantees the deployment of Portuguese troops to fortify the poorly defended Scottish border with England. Tomás finally states his father has always favoured him and will likely legitimize him, since the current heir is the king's 3-year-old grandson; this will make their match politically acceptable. Mary, who cares deeply for her betrothed, Francis, accepts his proposal, albeit with doubt on her face.
Later at a banquet, Tomás interrupts a dance between Mary and Francis, insisting on having a dance with her. He then commands the musicians to play a Portuguese piece, and procedes to lead in her in a provocative dance of lifts, dips, and seductive body contact. Greer is crushed, and despite Mary's attempts to comfort her later, the relationship between the two tears. They later reconcile, however.
Mary tells Tomás that her family needs to confirm everything he's been telling her, even though his ship has several companies of men that can leave the following day. Mary agrees to the engagement and sees the dragon flag of one of his ships - the (English) lion will fight the (Portuguese) dragon on a field of poppies.
In Hearts and Minds, Tomás reveals his cruel side. He becomes abusive of Mary, which angers Francis. Francis is suspicious of Tomás, and with the help of Bash and Mary, it is discovered that Tomás was the one who had informed the English that Bash and groups of soldiers were going to defend Scotland (Tomás is responsible for Bash's near death injury). Tomás is killed by Francis, after Tomás tried to kill Francis and Bash.
At first Tomas seemed to be a passionate and kind man with a playful and adventurous side. He turned out however to be a cruel and sinister man who doesn't care for anyone but himself. He lied about his true self and intentions to get what he wanted, showing that he is also a manipulator.
Tomás is a dashing man probably in his early thirties and has dark brown hair, blue eyes and and has tan skin. He dresses elaborately like all lords do.
