As Boston Blue prepares for an explosive season finale, Sonequa Martin-Green teased a difficult revelation. "What a journey I take as Lena Silver. There's some threads of it at the beginning of the season [and] you'll start to see us delving into some really serious things," Martin-Green exclusively told Us Weekly about what is still to come. Martin-Green warned that there "were difficult stories to tell." "I applaud Brandon Sonnier - our coshowrunner - because the Silver family is based on his own family. There are a lot of dynamics in Lena's life that are based on his life," she continued.
