So I finished the Inheritance Cycle (the Eragon series) the other day and my favorite character is Angela the Herbalist, who I'm absoutely certain is a Timelady (like from Doctor Who). I didn't suspect anything until I read to the part that it last says. All of the evidence is shown here (for some reason with a black background):

There is also significant evidence to suggest that Angela is meant as an homage to the long-running science fiction series Doctor Who. After Brisingr, Christopher Paolini admits to including at least one Doctor Who reference in-story (specifically, the line about the 'Lonely God adrift upon the Sea of Time') and several more appear in connection to Angela. The main character of Doctor Who is the Doctor, a man whose real name is unknown and who belongs to a quasi-immortal race known as the Time Lords. Solembum mentions to Eragon that he has seen many strange things with Angela, including rooms that are "bigger on the inside" than the outside would suggest, a quality ascribed verbatim to the Doctor's TARDIS or space-time ship. Angela is also shown to have control over at least her own passage through time, a technique she uses against soldiers in Dras-Leona. Like the Doctor, she is exceedingly eccentric and effervescent and often makes seemingly random statements in a completely matter-of-fact way. She also has a youthful appearance despite an age on par with or exceeding that of the average elf, a quality shared with the Time Lords. She speaks nearly every language in Alagaesia, the Doctor himself being able to speak almost every language in the universe, is another quality they both share.
In the battle to escape the priests of Helgrind, she says to the chief priest that he wouldn't have dared face her if he had known who she was. She leans in and whispers something (presumably her real name) in his ear. He is horrified. In Doctor Who, the fact that the Doctor's name is a secret is a recurring theme and it's implied that his name reveals him to be someone horrible.
Finally, at the end of Inheritence, Angela is knitting a hat with the beginnings of a word on it, the letters "Raxacori". Raxacoricofallapatorius is the name of a planet in Doctor Who.
