If maybe this is Fergus seeing Claire for the first time the day after her night at the brothel with Jamie.
Just lookit his face! Like he’d just spotted her standing off to the side (with her not even realizing yet that Jamie was talking to Fergus)
Then he just walks away from Jamie mid-sentence, and we get:
“Milady!” he was repeating in tones of rapture. “Milady! You have come back! A miracle! God has restored you!”
He looked up at me, smiling as tears streamed down his face. He had large white perfect teeth. Suddenly memory stirred and shifted, showing me the outlines of an urchin’s face beneath the man’s bold visage.
“Fergus!” I said. “Fergus, is that really you? Get up, for God’s sake—let me see you!”
He rose to his feet, but didn’t pause to let me inspect him. He gathered me into a rib-cracking hug, and I clutched him in return, pounding his back in the excitement of seeing him again. He had been ten or so when I last saw him, just before Culloden. Now he was a man, and the stubble of his beard rasped against my cheek.
“I thought I was seeing a ghost!” he exclaimed. “It is really you, then?”
“Yes, it’s me,” I assured him.
