I didn’t say my name… No, but I did. His entire timeline is at risk in this moment, but as soon as River reveals she said his name, he freezes and his face falls. Absolutely falls. He can’t speak to her, he can’t say anything. She’s a ghost haunting him by his own choosing. She’s always there, he always listens, but he can never say anything in return. He’d rather have her there and never speak than face saying goodbye. He shakes it off and resumes the task at hand knowing full well this could be the end for their relationship, for his life… for everything.
