Caleb McLaughlin is getting candid.

The 20-year-old actor, who plays Lucas on Netflix's smash hit Stranger Things, opened up about the racism he's experienced since the show's inception in 2016.

"It definitely took a toll on me as a younger kid. My very first Comic-Con, some people wouldn't stand in my line because I was Black," Caleb said at the Heroes Comic Con in Brussels Sept. 25. "Some people told me 'Oh, I didn't want to be in your line because you were mean to Eleven (Millie Bobby Brown).'"
