“Fair friend,” said she, “rise up, for no longer may you tarry. The hour is come that we must part. But one thing I have to say before you go. When you would speak with me I shall hasten to come before your wish. Well I deem that you will only call your friend where she may be found without reproach or shame of men. You may see me at your pleasure; my voice shall speak softly in your ear at will; but I must never be known of your comrades, nor must they ever learn my speech.” Right joyous was Launfal to hear this thing. He sealed the covenant with a kiss, and stood upon his feet.
The maiden is speaking to Launfal but is referring him as "fair friend." Before the maiden and Launfal are about to go separate ways the maiden is making a statemen, about how Launfal can see her whenever he wants but his companions can never know of it or her. Where it says "but I must never be known of your comrades, nor must they ever learn my speech" she is setting clear boundaries about how they meet, when they meet, and this secret is clearly between them two. Because the two of them are a secret it gives the idea that their "relationship" is intimate. The words of "Well I deem" and "Without reproach or shame of men" gives the language from the medieval time.
