Derek was a little startled at the sudden hug and rush of emotion, though he caught her and tentatively patted her back soothingly, still a tad bit stunned at the force of her gratitude but glad he could help and make someone feel so thankful.
A tiny, tiny giggle escaped her at Isaac’s whine and wiggle, and then she paused, frowning in surprise and amazement. Lifting a hand to her throat, she tried to say something, but nothing came out.
Isaac wiggled until her hands lifted, and Derek’s head came up off the pillow as she giggled. His eyes went wide a bit as he grinned at her.
She tried again, brows drawing down, as her fingers tapped at her throat. When nothing came out again, she slumped into the pillow, heedless of the fact that she was still half draped over Isaac. After a moment she flopped over into Derek’s chest, staring up with a woebegone expression.
