Bellamy Blake: The first time you met Bellamy was after you landed on Earth. You were one of the 100 sent to the Earth with Octavia being your best friend. She was also the one who introduced him to you. You and Bellamy had met briefly at the masquerade when you were trying to find Octavia, asking him where she was.
Finn Collins: You met Finn when the two of you were on your way to the ground. Finn passed you when you were sitting on your seat, sending you a wink before continuing his 'travels' around the drop ship.
John Murphy: The first time you and Murphy locked eyes was when you were siding with Clarke and Wells, telling the others that you all should go to Mount Weather. He didn't agree with you; therefore the two of you spent the whole incident glaring at each other and throwing sassy remarks at each other.
Jasper Jordan & Monty Green : You, Jasper and Monty met while being on the Ark. The three of you were best friends, having met when you were seven, they being older than you. You didn't meet each other until you all were being sent to the ground for a second chance.
