Why is Joseph Quinn crying?!

In this interview, Joseph Quinn, who plays Eddie Munson in Stranger Things 4, kept drying tears from his face. Perhaps it is only some allergies or he's getting a cold, but he looks so SAD!
What do you think?
He was doing multiple 5 minute interviews in a row, so it could have been something happening in a previous interview, but I have not found it yet.
