How does Gilbert respond to the presence of Helen and Arthur as he meets them shortly thereafter?

From the text:

But I did not visit it that day; for, as I approached, I beheld, at no great distance, Mrs. Graham and her son coming down in the opposite direction. They saw me; and Arthur already was running to meet me; but I immediately turned back and walked steadily homeward; for I had fully determined never to encounter his mother again; and regardless of the shrill voice in my ear, calling upon me to “wait a moment,” I pursued the even tenor of my way; and he soon relinquished the pursuit as hopeless, or was called away by his mother. At all events, when I looked back, five minutes after, not a trace of either was to be seen.
