You see this gif? This gif right here? I could look at this gif forever, you know why? It says so much. The doctor is in such a vulnerable position, for him it looks like everything is lost. He just walked in onto a full Dalek fleet, the most that he’s seen since the Time War. For all he knows Donna is dead and the Tardis is destroyed. And then Rose walks up to him and grabs his hand. Look at the way he grabs her hand and then squeezes it. He needs Rose so much, because to the Doctor, having Rose there gives him the courage that he can work his way through this, and he can still save the day. If Rose can jump from dimension to dimension just to find him, then the Doctor can save the world. And look at the way that Rose strokes the Doctor’s hand with her thumb, ugh. So sweet. I can’t even. She wants to do everything in her power to make sure the Doctor knows that she is there, because she knows that he needs that reassurance. And she does too.
