"My sons, what's going on?" Splinter asked, seeing them carrying the unconscious winged teen to Don's lab.
"He came through a portal." Leo answered as the turtles set the boy on the bed. Don quickly grabbed a wet cloth and pressed it against the winged boy's forehead. "He came through the portal headfirst, knocked himself out and now he's bleeding from the forehead."
"Leo, go on patrol without me." Don spoke softly "I'll take care of this guy." Leo swallowed hard, his brown eyes locked on the unconscious teenager.
"Leo, I'll stay with Don." Raph said, his amber eyes locked on the boy "Just like you, I don't trust this guy." The eldest turtle sighed heavily as Don puts a small bandage on the unconscious teen's forehead.
"We'll skip patrol." The olive green turtle slowly looked at Leo "We don't know this guy. When this guy wakes up, we have to find out who he is and why he's here." The blue masked turtle quickly looked at his dark green brother "Raph, stay in the lab with Don and keep an eye on our visitor. Mikey, Splinter, and I will be in the living room and when he wakes up, we'll come in." Raph nodded, watching his elder brother leave.
….
Don quietly examines the unconscious teen as Raph sighs heavily.
"Anything wrong with him, Donnie?"
"The only thing he has is a couple bruises on his hands." The olive green turtle slowly looked at his brother "I'm guessing he was fighting with someone before jumping through that portal." Raph looked at their visitor's hands, seeing that the boy has three fingers, just like him. "His wings are perfectly fine." Don slowly removed the bandages off the boys head "Plus the bleeding has stopped." The winged boy loudly groans as the two turtles stare at him "Raph, he's waking up."
"Ya want me to get the others?"
"Yeah." Raph ran of the lab as Don quietly watched the teen groan. The boy's eyelids slowly opened, revealing olive green eyes. He groaned again, trying to sit up. "Y-You shouldn't get up so fast." The winged teen quickly looked at Don and swallowed hard as Raph ran in the lab with Leo, Mikey, and Splinter.
"All right…" Leo spoke softly "…before you do anything…tell me your name." the boy quickly wiped his wiped his eyes and swallowed hard.
"It's William."
