For a few seconds he could only stand and stare at her, involuntarily holding his breath. After a few moments he took the step forward to brush his hand against her temple in a traditional Gallifreyan meeting, the touch confirming what he already knew. It was Romana.
He didn't know what to say. In that moment, it was as though he'd forgotten how to form words, his mouth opening and closing but nothing coming out. Eventually, he moved forward again and wrapped his arms around her, placing his forehead on her shoulder, his fingers gripping tightly at the fabric of her shirt.
