Abducted (rottmnt fanfic)

Donnie finds himself in a confusing and terrifying situation after the group splits up and his solo mission goes wrong, no one can find him and he won't reply to anyone's messages. There are few clues about where he could've gone and where he went is up for speculation to family and friends.
No one knows where he is except for Donnie himself, who was taken by scientists. They seem to mean well, but don't see him as a person.
