Bo and Sophie

Bo and Sophie Hudson are Tilly's missing parents.

They are the original owners of the Locomotive that Tilly now operates. It is unknown what happened to her parents and why the locomotive was abandoned and in disrepair despite Bo and Sophie not returning to Tilly and her Grandmother's home, where the abandoned locomotive was found.

When Tilly was a very young child, her parents left her in the care of her Granny. They left in a rush, while acting nervous, and left a recorded voice message for Tilly on the voice box of her Mattie Doll. During the voice message, her parents said they hoped to be back soon, yet they were uncertain of how long they would be away. The mentioned needing to go someplace far, far away. They then hid the voice box in the trainyard.

They would frequently send Tilly journals which told of their travels and discoveries.

Despite their absence in her life, Tilly holds no resentment toward either of them.

Tilly eventually receives a letter telling her that her parents are not ever returning to reunite with her, however the letter does not tell her why.

### Trivia

* According to Emily and Roger, Tilly's parents never mentioned ever having a daughter, despite the fact that they were close friends.
	+ Additionally, they were close enough friends for Bo and Sophie to confide in them with secrets that even Tilly does not know about them.
* According to Remi, Bo and Sophie planted a tree near his orchard and named it "The Tilly Tree."
* Sophie lost her Golden Nameplate Necklace, which is presumably later recovered by Tilly.
* Sophie plays a role in the Mothers Day event during flashbacks. During this event, a profile picture of Sophie could be obtained as a reward for completing all of the event tasks.

### Speculation

* It is currently unrevealed whether Bo and Sophie are still living or deceased, however it is strongly foreshadowed in Tilly's second eerie dream when her mother spoke to her, saying, "Tilly, save us!" heavily suggesting that Tilly's parents are still alive.
* It is possible that Tilly's parents left her behind to protect her, since their travels were dangerous. This is supported by the attack by raiders on Tilly upon leaving the Old Rail Yard and also by her near death experience in the Basinbarrow Ruins, a place that her parents had written about their exploration of.
* It is also possible that Bo and Sophie's locomotive was discovered elsewhere abandoned and then transported to the Old Rail Yard, which appears to be a place for broken and unwanted locomotives to be stored.
* Later in the story line, Tilly reads an inscription on an ancient mural in Poppy's Sacred Cave, which reveals that Word Wielders are being hunted and killed. One could presume that one of Tilly's parents, or both, are Word Wielders and have to stay moving to avoid these hunters, which would support their motive for travelling without Tilly, isolating her from the rest of the world, and keeping her a secret by not telling even their closest friends that they have a child.
	+ Granny, the late mother of either Bo or Sophie, was heavily implied to be a Word Wielder. Poppy, the other mother of either Bo or Sophie, has been reasonably indicated to also be a Word Wielder. One could interpret this as a coincidence, or more likely that there may be a genetic factor, as being a Word Wielder seems to be hereditary; which would firmly rationalise why they needed to keep Tilly's existence hidden, as if being a Word Wielder was a choice they would have merely not mentioned it and as a result had no need to fear for her safety.
	+ Given the inclination of dominant genes, Poppy is likely Bo's mother, while Granny is likely Sophie's mother. However, there are irregular outliers in gene pools.
* Bo Hudson's height could be inferred to be approximately 200cm [6'5"] not including his hair fluff, when interpreting the officially released height chart.
* It's likely that the letters and packages that Tilly's parents sent to her had no return address listed.
