Re: We fear nights and death.
"Brother, I could kiss you." Thor pulled Loki as if he might actually do it, only to release him before they were too close. Thor stood, a renewed bounce in his step and turned to address the trickster god again. "I'll track this down immediately, I swear." He spoke as though this would cure all that ailed them, when it might only complicate matters. The Allfather needed this poison to be removed, preferably before Yule. "Stay here, please." Thor instructed, fifty/fifty whether or not Loki would listen.
"Anything but solitude."
"I would miss our chats too much, Loki." Thor encouraged his younger sibling. "I've worked much too hard to reunite this family," he added as actual encouragement, just before he vanished back to Vernal Asgard.
