One of the most romantic things Remus could do was to Tonks was hold her hand. Yes it was simple and to most people, probably not romantic at all, but to Tonks, it was the most romantic thing in the world.
She loved the closeness she felt to him, and the connection she felt with his body. Remus loved watching Tonks when they were holding hands. She was always smiling and her hair was always a vibrant shade of blue...Remus' favorite color. Remus felt close to Tonks as well. He seemed to be able to tell how her mood was, by how long, or how tightly Tonks her held his hand.
On the night of the Battle of Hogwarts, Remus and Tonks fought together. When they began to duel Dolohov and Bellatrix, Tonks reached for Remus' hand. They both knew that these were their final moments and wanted to feel the closeness that they both loved so much. The Killing Curses were fired at the same time, and together Remus and Tonks fell to the ground, hands entwined tightly together.
