Leo, Mikey, Raph, and Donnie were all doing their own things separately, until they heard Splinter calling them; Splinter told them that he had found a boy/girl in the sewers, near where they were
The four of them looked at each other confused, but Splinter continued explaining that he had brought him/her because he saw potential in him/her... After the explanation, Splinter said he would leave for a moment so they could get to know the boy/girl better

Mikey: "Are we getting a new brother/sister?"
He said enthusiastically, thinking that he wouldn't be the youngest brother anymore

Donatello: "Maybe I could use him/her as a guinea pig..."
he muttered to himself, although several of them heard him

Raphael: "Donnie, you're not going to use anyone as a guinea pig, got it?"
He said while crossing his arms

Leo: simply laughs, although he felt some nerves about the news
