Should+they+follow+Savannah+into+the+house?

RMe and Macey with no choice but to follow her. We walked into the living room where she stopped “AGHHHHHH!” I look behind me where the scream had come from, the immediately realized that Macey was gone! “Macey”?! I holler. No reply. I hear footsteps and a very faint shadow disappear up the stair case.

Should Raegean and Savannah follow the mysterious shadow up the staircase to find Macey? or Should Raegean grab Savannah and run home?
