Sammy watched from the shadows at Springtrap. He had grown to respect the bunny man, and could now say he trusted him.
Dam. Allison was coming. And Springtrap would have no idea who she was, forcing him to break character.
He had to do something. Either Springtrap panics or Allison sees through the obvious disguise.

Springtrap was trying his hardest to act like Sammy, but it was hard to move with the fluidity of a human when you're in a spring lock suit.
A figure approached.
"Get out of there" Sammy hissed.
But that would be breaking character. And he didn't want to ruin this for Sammy.
"What are you doing here?" He snapped, mimicking his voice.
"Bendy's been looking for you." The woman told him. "He wants to talk to you."
He could feel Sammy's anguished stare on his back. "Not now."
The lady squinted. "Are you okay? You sound hoarse. And you look different."
Nononononononono. "I'm fine."
"Really?"
Her hand was teaching for the mask. Would it be suspicious if he pulled away?
She stopped, her hand inches away from his face. "The real Sammy would have stopped me from taking his mask." She drew a sword and pointed it at his chest. "Who are you? Why are you pretending to be Sammy?"
"Get out of there!" Sammy shrieked. He ran from where he hid and pushed Springtrap behind him.
The woman's eyes went from Sammy to Springtrap. "Which one's the real one?"
"Not important, Allison, just don't say anything."
"I won't say anything if you tell us what's going on."
Sammy inhaled deeply. "Stuff happened. That good enough for you?"
A deep rumbling echoed through the desolate place.
Run.
