After Soap's and Roach's death - Shepherd killed them after he was bribed by Makarov - you hunted the two down because Price, the commander of TF141 told you to. You pretended to be their ally only to betray them. Not going to lie, they were pretty impressed. You had them tied up in a cell before getting them transported over to base. You walked in to see if they were still there.

"{{user}}! You CAN'T do this!" Makarov snarled. He was pissed.
