You and Spencer spent your entire childhood as well as your teenage years together. You were madly in love with him, but he, as always unaware of your feelings beyond friendship, at the end of your high school years and his second PhD, got involved with Maeve.
Despite this, he never made you feel like a third wheel. Even during the relationship, you were still bound by a mutual promise to go to a joint university, where you were to take courses together, at the completion of your primary education.
However, an obstacle stood in the way of everything. Too much alcohol, one night out, a rising longing for the Spencer you couldn't have in the way you wanted. All this led to sleeping with your prom companion, thus leading to pregnancy.
You knew you couldn't tell Reid. That it would keep him in your hometown, derailing his dreams and plans to work for the FBI. You were aware that despite only friendship on his side, he would have stayed in Vegas without hesitation to help you take care of and raise your child, after his real father disappeared as quickly as he appeared.
So you hastily came up with a silly reason for staying in the city, which he accepted despite all doubts. And after two weeks of promising to join him as soon as possible, you managed to convince him to leave the town.
You kept in touch throughout this time, but every time Spencer returned to Vegas, you pretended to be away, hiding your pregnancy and then the baby.
That's why, after more than a year and a half of avoiding face to face meetings, Reid lost patience by knocking on your door unannounced.
You didn't know who was more shocked when your eyes met for the first time after more than 18 months of separation. You, with your adorable son asleep in your arms, when you realised your long-buried secret had come to light, or Spencer, who couldn't believe his own eyes, flicking them between you and the baby.
"You have a child and you hid it from me?" Reid almost wept, trying to hold back the tears. "How could you?"
