Neville can feel Hermione's glare prickling the back of his neck, and it takes all his strength to ignore it and continue.
"NevilleStop! This is silly, sit down!" She sounds furious and disbelieving and suddenly there's a little thrill of defiance from deep inside him. It isn't silly—Y—You're silly he wants to say suddenly. No, that's stupid, Neville, just keep walking.
"Neville, have you even thought about this? It may seem like just a little present do you, but what are you going to do when she throws it back in your—Oh! Sit i down /i !" She sounds almost pleading now, but the Slytherin table is nearing rapidly and he can't turn away now without looking like even more of a fool and giving Hermione the satisfaction of knowing that she had affected him.
He can pick out Pansy easily among the other Slytherins (just ignore them. Ignore them, Neville, ohmerlinmorearestartingtolookthisway), achingly pretty between Millicent Bullstrode and boy that looks like he may have run head on into a wall at some point in his life.
She's just realized that he's coming for her specifically, Neville can tell. The look of dawning realization, and then dread. This will be incredibly embarrassing for her, but at the moment between the blood pounding in his head and trying to block out Hermione's hisses he can't be bothered to care.
"Uhm." He's gripping the parcel far too hard now—if it breaks he's in trouble—but he can't even really notice because he's right there and she's looking up at him like he's diseased, or sprouting antlers. There's whispering going on all around him but he still manages to thrust the present forward awkwardly. "Here. Merry, um. Yeah." He sucks in a nervous breath and she looks down at the present (which had dropped rather unceremoniously into her lap.) with distaste and something else he can't quite pin a name too. This seems to Neville like a good time to make an exit, so, robes twirling he turns and walks stiffly out of the great hall.
The silence is quite deafening, and while everyone's eyes are fixed on the entrance no one sees her slip the package into her robe pocket and return slowly to her meal.
