Right after finishing school, you leave the building. But immediately get a text right as you're about to head home.

Leo > Klayne, please come meet with us behind the school dumpsters.

It was Leo, the turtles leader in blue.

Whatever they wanted, you trusted them enough to go. And see for yourself.
