Flint didn't leave his stance of looking through the scope at the recruits. Even when Yuki left to intervene with a source Gastrea. He always felt incredibly comfortable around her and even if he doesn't notice something he knew Yuki would. He was busy anyway, he was watching the fight moves, the teamwork. He wouldn't say it out loud but they where rather good, maybe even to match himself and Yuki.
Yuki returned "Are they done yet?" 
"Yeah, target destroyed" He muttered as he removed his phone from his pocket
He called the company and asked for a Gastrea clean up crew than texted Kiri writing.
"Recruits have successfully defeated the Gastrea, Yuki has defeated the Source. All recruits have passed" He sent the text then looked to Yuki 
"Ok lets go down and tell them the horrible news, that they have been accepted" Flint joked as he began to walk to the steps, refusing if Yuki attempted to pick him up once again.
