He won't lie: he's not surprised when Beast Boy approaches him, asking if they could go all out decorating the Tower for Christmas this year. What does surprise him is the presentation: detailed drawings and lighting plans, well thought-out and actually rather feasible (though the strategic mistletoe placing program makes him wary).

Robin listens silently, and he's quiet for a few moments after the shapeshifter finishes.

Finally, he asks: "Why are you so intent on doing so much this year in particular?"

Beast Boy shrugs and looks at his feet sheepishly. "It's Terra's first Christmas here… and I don't think she's ever actually celebrated it before."

Robin immediately wonders why he didn't consider this himself, and almost delves into his own thoughts before he remembers Beast Boy's still standing in front of him, waiting for an answer.

He smiles. "I think it's a great idea."

Come next week, Beast Boy is leading Terra outside with a blindfold. She's laughing and asking what on earth he's up to, while the others watch on. Robin catches even Raven smiling under her hood. Finally, Beast Boy nods to Robin, who flips the switch that sets the entire island aglow in multicolored brilliance. Beast Boy removes the fabric from Terra's eyes.

While the Tower's lights are nothing short of dazzling, Robin is almost certain the light in Terra's eyes comes from her radiant smile, its power brightening her entire face.

I've been waiting to post this for months. :) Happy holidays, everyone!
