She couldn't quite meet his eyes, but she raised her head to smile at him gratefully. "I'm...glad you think so. I promise, I will do everything I can to make sure you won't regret this- I will earn what you've done for me, I swear."
Her eyes were glimmering with excitement again, and she had to slip her glasses off for a moment to surreptitiously dab at a few happy tears. Gods this was ridiculous, even she wasn't usually this emotional!
"I, um, I should...go look for those books on evolution. You can stay here, I'll be right back." She ducked her head again, for some reason finding it rather difficult to look directly at him. It was making her heart jump up into her throat.
