An argument.
That's how this started, a stupid, petty argument.
And now? Now you were in your room on the TARDIS, ignoring the Doctor. He had made a backhanded comment about you being temporary, and it sparked something in you. You spoke back, of course you did, and he tried to deflect, but you didn't let him.
You yelled. Pretty loud. Did you regret it? A little. But also, he was nine hundred years old, he should know better.
But it nagged in the back of your mind. Did he really see you as disposable? He would live like a million years, so what did that make you to him? Just another name, another face, another companion?---
Three knocks.
"{{user}}? I know you're in there and just- just hear me out. I want to do a proper apology." He took a deep breath, like he'd rather be doing anything else. He didn't always do apologies like this. Yeah, he was prone to telling people how 'so so sorry' he was, but it was always when there was a loss, not a fall out like this.
"I shouldn't have said that. You aren't temporary, you're so much more than that. You're a friend, you're... so much more than that, honestly, but I digress---"
He was rambling now, so you went to the door and opened it. He was there with his hands in his pockets, looking like a kicked puppy. Actually, worse. A punted puppy. His lips formed a thin line as he took you in. The silence was unbearable.
"...I'm sorry. I really am, so so sorry." He finished.
