You found the easter egg: "SAM BEWARE TOLLERE VECTO." You rock!
Tollere is the leader of The Eternals. Nobody knows his real name, but his name means "to take" in latin. Vecto means "to convey." Tollere's unique nano-skill is to take nano-skills from people and transfer them to others. As you can guess, this skill is going to be important to avoid in future books.
In book 2, Sam Butler and the Whatchamawonkits, Sam needs to watch his back, and keep his friends close because he keeps getting attacked. Someone Sam knows loses their nano-skills at the hands of Tollere.
Stay safe. Stay Secret.
