"Growing Pains" - Loki + Thor (AU movie!Marvelverse) - {Chapter IV}

~

A/N: …And as I wrote this chapter, I discovered that there was a LOT more story here than I’d first thought. I was planning on sort-of glossing over their ~GREAT QUEST~ but…I liked the idea so much that it took off and carried me with it. So apparently we’re gonna have this crazy ZOMG YEY ADVENTURR detour, and then have a go at the more crack-y aspect.
