General Hospital spoilers, March 7: Lulu puts Brook Lynn in the hot seat

Here are your General Hospital spoilers for Friday, March 7.

What to expect on General Hospital

After talking with Carly (Laura Wright), Lulu (Alexa Havins) still doesn't know what to do with the knowledge that Brook Lynn (Amanda Setton) had Dante's (Dominic Zamprogna) baby as a teenager and never told him. So, she heads to the Quartermaine mansions for more answers and confronts Brook Lynn. As soon as Brook Lynn realizes that Lulu is gunning for her, she asks to take this confrontation somewhere private.

Brook Lynn is stunned to learn that Lulu discovered her secret and wants to spill it. Lulu warns Brook Lynn that if she doesn't tell Dante that he has another child out there somewhere, then Lulu will do it. Brook Lynn has to make her case to Lulu that some secrets are better left buried, but Lulu is determined. Hopefully, Brook Lynn can tell Chase (Josh Swickard) the truth before Lulu does.

Ned and Lois clash

Ned (Wally Kurth) and Lois (Rena Sofer) have been the perfect co-parents all these years, but are they the perfect co-grandparents? Does Ned even know he has a grandson living with him?

He tells Lois that this time, Tracy (Jane Elliot) is right. She knows where Sonny's (Maurice Benard) money comes from and can understand his mother not wanting blood money to pay for Gio's (Giovanni Mazza) education. After coming from Sonny's house, where they discussed the same thing, Lois is just about done talking about Gio and his benefactors. Do we learn the reason that Sonny has been taking care of Gio all these years?

A dagger before her

Like Macbeth, Alexis (Nancy Lee Grahn) sees a dagger in a castle and wonders where it came from. Sidwell (Carlo Rota) wants to gift it to her, but Alexis wants to know where this dagger came from, knowing it is the one Helena (Constance Towers) used to kill her mother. Julian (William deVry) also held that dagger to Alexis' neck when he faked trying to kill her for Olivia Jerome's (Tonja Walker) sake.

How did Sidwell find this dagger that Alexis was sure was gone forever? How is Sidwell really connected to the Cassadines?
