The guest stars are piling up and lending a helping hand on tonight’s all new Girls season 4, episode 7.

Girls is no stranger to jam packing seasons with guest stars and tonight we finally get Zachary Quinto in the mix. Tonight’s Girls season 4, episode 7, “Ask Me My Name,” lends a hand as Hannah, Adam, and Mimi-Rose participate in a local volunteer day.

Previously on ‘Girls’

Hannah and Ray set themselves on a new course, while Adam reevaluated the one he currently found himself on. Mimi-Rose announces very bluntly that she had an abortion and therefore could not go running with her boyfriend. When Adam begins to question just how much he is needed in his own relationship, Mimi-Rose urges him to reconsider his future with her. He may be needed, but is he wanted?

Meanwhile, Hannah contemplates a career move into a field that will allow her to help others after speaking with her therapist and friends. Ray’s trip to the city board not only gets a rise out of the community, but makes him consider running for election and making a real change in his neighborhood.

It seems like the desire to get along and give back is contagious. Hannah’s new job puts her in contact with Fran, played by Jake Lacy, with whom she becomes fast friends. After exploring an offbeat art show with her coworker, a volunteer event puts Hannah, Mimi-Rose, and Adam in the same location. But the awkwardness does not end there as Ace, guest star Zachary Quinto, sets Adam on edge. Shoshanna and Ray are full steam ahead as they prepare Ray’s community board campaign.

How much altruism really exists in the Girls universe? Tonight will certainly be the first test of how selfless each character can be.

Watch Girls season 4, episode 7, “Ask Me My Name,” tonight at 9:00 p.m. ET on HBO.
