clever_wanderer asked for confused!Sarah. So!
“I don’t understand, Doctor.”
Sarah Jane frowned, staring up at the man in front of her. He ran a hand through his hand, a nervous habit of his she had come to recognize as a sign of imminent awkwardness. She sighed, glancing down at the small box in her hand. She hadn’t meant to do that, to put him on the spot like that. She just… well, to put it simply, she didn’t understand.
“Why?”
“I… er, I…” He was stuttering. At the very least, Sarah knew that she had to be thankful that he hadn’t started talking about the weather yet. “Kinda stumbled along it the other day, going through the c box. I figured it was about time for a reread of Murder on the Orient Express, given that I can’t spend all day working on the TARDIS and I--”
The Doctor shrugged, smiling faintly. Sarah may have been confused by the small gift, but by now she had at least learned, and understood, the trouble he had with words sometimes. Babble was one thing. Emotions were something entirely different.
“ It’s been brilliant, having you here that is. I’ve told you that, haven’t I? And I just want you to remember. That I always want you… blimey, are those really tears?”
They were. She smiled weakly as she brushed away said tears. It had become habit now, hadn’t it? Confuse her, make her cry. Still, she doubted she would have it any other way. The box fell from her hands as she fingered the silver Claddagh ring. “It’s lovely, Doctor.”
“’Let love and friendship reign,’” he whispered. “Never forget me when you wear this ring, Sarah Jane Smith.”
