The Bold and the Beautiful What-to-Watch Moments, July 4: Luna vs. Steffy...and Sheila?

What to expect on The Bold and the Beautiful

Fireworks will be on display inside a little beach house doubling as an art school for four-year-olds. Steffy (Jacqueline MacInnes Wood) makes her way there, hoping to get answers about Miss Sunshine from Miss Dylan (Sydney Bullock), but she does not expect to find her loony stepdaughter standing there with a gun.

Steffy does her best to reason with Luna (Lisa Yamada), but that is easier said than done. Luna is more insane than ever and knows exactly what she wants to do. She even dressed for the occasion and donned her green leather getup. That's now her official "Kill Steffy" outfit, but Steffy has no intention of getting killed.

Luna has no idea that her devoted grandmother is also determined to stop her. Thanks to Remy (Christian Weissmann), Sheila (Kimberlin Brown) knows that Luna is gunning for Steffy and begs Taylor (Rebecca Budig) to tell her where Steffy is. Taylor doesn't want to give Sheila any information, but Sheila manages to convince Taylor that she is on their side and only wants to keep Steffy safe.

Steffy will be stunned when Sheila appears at the beach house. Does she wonder if she will have to battle both of them?

An alarmed Liam?

Liam (Scott Clifton) is just starting to focus on himself again when Ridge (Thorsten Kaye) pays a visit to the design office to lament about Luna and what happened with Will (Crew Morrow) during the sting operation. Ridge is more worried about Steffy than ever, but will his fears give Liam unwanted stress?

Ridge doesn't know that Liam is suffering from a fatal brain tumor, but he may still find out. Liam has been worried sick about Steffy and practically appointed himself her protector when he is in no condition to be protecting anyone. Will Liam decide he has to spring into action or will just the thought of springing into action cause an episode that makes it obvious he is suffering?

Hope (Annika Noelle) has been urging Liam to come clean about his illness. Maybe he won't have a choice.
