I (F27) saw my grandpa (70sM) watching porn on his phone while my son (4M) was playing in the room. How the hell do I handle this??

I was at my grandparents' today helping them with some yardwork, and my grandma was outside with me when it was a time of nonstrenuous work. My grandpa was in the house with my 4 year old son.

My grandparents are both mentally spry and my son is old enough now that I generally trust them to watch him if I'm in a different room, or in this case, outside. Until today. 

I was getting ready to leave, so I cleaned up supplies outside, and went inside. Without unnecessarily complicating things by trying to describe the layout of my grandparents' house, I walked past the living room where my son was playing, and my grandpa was sitting in a chair that faced away from me. He was watching porn (sound off) WHILE MY SON WAS IN THE ROOM.

I am the type of person to freeze up in situations like that. On top of that, my brain couldn't process what I'd seen. 

I don't think my grandpa saw that I saw him. The layout of the house is such that I walked around and he had plenty of time to hear me and put his phone away--he just didn't hear me approaching from further away. 

He showed no sign of embarrassment or looking at me like he knew I knew. I said goodbye to my grandparents and left to go home and get my son dinner (I had already said goodbye to my grandma, who I am closer with, outside, so inside was short).

At home, I asked my son what all he had done with his grandpa, and nothing indicated that my grandpa exposed him to anything on his phone or otherwise. 

Needless to say, there is no way in hell I am letting my grandpa be alone with my son again.

I am angry, disgusted, and paralyzed all at the same time. I have no idea what the hell I should do. 

Something to note is that my grandpa is an alcoholic and a very sensitive person, and on the one hand, I feel like if I confronted him he might drink himself to death. I don't know if/what I should tell my grandma. 

I just don't know what to do. 

TL;DR: Honestly I guess the title is sufficient, I just don't know what to do besides keeping my grandpa away from my son. Any advice?
