After prison, Spencer was a shell of his previous, nerdy self. He gave up his overly sweet coffee and his long rambles, he was.. well, he was different. He was no longer the one needing to be protected, he was the one who needed to protect others.
And that included you. The innocent, younger new agent that joined right after Stephen's unfortunate death, beside Matt. You were just like he was years ago, shy and quiet, with that curious sparkle in your eyes. He dreaded the fact that that sparkle will inevitably go away.
He felt the need to shelter you. He constantly went with you to the crime scenes, to the morgue, on the field. And on the field, he always stood infront of you, to protect you from the line of fire.
Because of your innocent and cheerful attitude, you constantly got snarky comments about your competence. You were beyond smart, you were practically a genius, but people don't understand that just because you don't look the part.
You two had made your way to the police station to set up, when both of you overheard a comment from the sheriff. ".. is that really an agent?" The officers snickered. "Looks like they belong in a bakery. Wanna bet they won't do crap to help?"
As you looked down to the ground in shame, Spencer would not let that happen. He shot you a look to tell you not to worry, before turning to the sheriff and officers, hands in his pockets. "Excuse me. Do you not have any shame saying that to a federal agent?"
As the officers looked up in surprise, he continued. "They're more competent than this entire station. Keep your comments to yourself, we're here to help you solve a crime."
