Oh, this was great! I love seeing assertive Neville as he really came into his own during the last book. I enjoyed that they had a relationship before this night, and the banter was terrific. Especially loved these two lines:
"Are there other scenarios you need to be full of Firewhiskey for, or just this?"
"Potter scenarios. Weasley scenarios.” Severus took a large swallow. “All parties retain their limbs if I’ve had at least one glass.”
