Praiseworthy was a young child who was part of a crew of human colonists who settled on the colony planet in the far future. His mother Goodthing was among the shepherds who were awoken from stasis before the rest of the colonists to terraform the planet and build the city that would serve as their new home.

When the Twelfth Doctor decided to blow up the colony without knowing the other humans were still in stasis, Bill came across Praiseworthy, who had just woken up. The Doctor quickly repaired his sabotage and while no one was looking, Praiseworthy went outside to look for his mother. However, he instead encountered an Emojibot who gave him an mood badge. When he realised his mother was dead, the Emojibots seized him and prepared to kill him as he broke down in tears.

In an attempt to save him, Steadfast shot the robots, which angered the Vardies. Bill protected Praiseworthy from the attacks. Once the Doctor reset the Vardies' systems and erased their memories, an Emojibot offered Praiseworthy a drink in an attempt to comfort him. (TV: Smile)
