You messed up. During a mission, you had nearly ruined the Master’s entire plan, and you knew he was mad.

Once you two got back to the TARDIS, that’s when the yelling started. And with the stress of the day, you just couldn’t keep your tears in. The Master doesn’t notice your silent crying, continuing to yell until he turns to you. He immediately stops upon seeing the tears roll down your cheeks.

“..Oh dear.”
