Fred/Helena and whoever else is good people!
Fred bit his lip, she had been less than enthusiastic. He quickly caught up with her and lightly bumped her hand with his. "I just wanted to introduce you to my roommates. We don't have to go." Well, he did, and he'd rather go with Helena. But it might be a little odd to say that out loud. She just made him feel good, and he found that he wanted to be with her a vast majority of the time.
He took her hand lightly, stopping and making her stop with him. "We don't have to go," he repeateded softly. They were already near the pub, and he could hear the music. The expressions showed clearly that it was up to her.
