Guys, I'm scared

Sam and Brayden just got back and they're in their gear covered in blood

If you're wondering what their gear is

Well is these

-Combat pants

-A leather jacket with little pockets on the sleeves 

-A bow and arrow

-Throwing knives x10

-Darts x5

But that's not why I'm scared they won't say anything they just walked in covered in blood they had little scratches on them but then they left 

I don't know what to do

should I follow them?
