The mistrust that floods her system almost outweighs the relief. She doesn’t trust Mona, especially after the way she seemingly got over how Alison treated her without a second thought. She trusted this Detective Wilden less, though. Given the choice, she’d rather pretend to tutor Mona - she didn’t need tutoring; Mona’s grades were almost as high as hers - than spend it being interrogated for something she had already been repeatedly questioned on. Her story never changed, and with her memory, it never will. Spencer meets Mona’s gaze with apprehension, curious as to why she was helping her. Now was not the time, however. Splashing a cheery smile on her face, she nodded her head. “I’m part of more clubs than most people have heard of, and I run most of them.” Turning to Mona, she continued with her falsity. “Actually, that’s why I came over here. We can start right now, if you want.” The teen had learned long ago that the key to telling a lie was to throw in a pinch of truth to the recipe. If you focus on the truthful aspects of whatever it is you were spouting off about, you could ignore the parts that weren’t so true. You can convince yourself that you’re not lying, you’re acting. Spencer learned from one hell of an actress, and this little lie is nothing compared to others she’s been convinced - or threatened - to tell.
Mona smiles widely at Spencer's complicity in the deceit. For a second there, she thought the other girl might refuse to go along with the ruse, and call her out in front of the policeman. It was a gamble on her part, but it was also the perfect opportunity for her to build trust, whether as an end in itself, or as an event that can be exploited. Mona pushes past Detective Wilden to stand at Spencer's side. When his penetrating gaze beams over them, she locks her arm around Spencer's elbow to give the illusion that there is no strangeness between them, and that all of this is perfectly natural. He does not seem to buy it, but she doubts that he will have courage to label two Rosewood High students liars in front of a crowded room.
"Spencer promised," Mona coos with big eyes, "You should know about keeping promises, Mr. Wilden, because I'm sure you had to take that Oath of Honor thing-y when you put on the blue uniform and promised to serve and protect." She takes a long breath, hoping that her Thespian performance was enough convince him it was not worth it to push for the interview. For extra measure, she adds, "I'm sure you can interview her some other day. It's not like we're going anywhere."
