Just started this quest today (XBox 360) and after meeting Eisa and being given the quest to investigate Frostmere Crypt, I instead decided to follow her to see where she went (I was loaded down with loot, etc and didn't want to do a dungeon crawl through the crypt).
She does indeed run back to the Moorside Inn at Morthal and enters the building. She disappears after entering, i.e., she's not inside when you enter the Inn, which I assume is the game's way of cleaning up an unneeded NPC.

To whoever manages this page,
When I met Eisa, she didn't go to the Silver Blood Inn but the Moorside Inn in Morthal.
She completely disappeared in mine :/
I met Eisa for the first time when I walked into the Moorside Inn in Morthal, and she instantly became hostile and I was forced to kill her and take her journal. Anyone have some idea why that would be? --LeDaea (talk) 04:19, April 29, 2013 (UTC)
