Found a skyrim easter egg in the Fallout Shelter app. (Yes I know they're made by the same company) it just caught me by surprise. Had to watch and wait nearly a month before this one character repeated it for a screen capture. Its a rather uncommon phrase.
If you're wondering how / where it happened: its Kayla Allen that is talking to Sharon Davis. (I didnt re-name random characters for this) this occurs in the super reactor room.
