Question: Who races upstairs?  Answer the above question based on the context below:  After seeing several patients, Travis, a troubled psychiatrist, is contacted at home by a patient, Rachel.  Travis invites her into his apartment, though he acknowledges this is unorthodox.  As they talk, Rachel sees Travis take several pills, which he explains are to help him deal with the mounting stresses in his life.  After they kiss, Rachel offers to help him, and Travis laughs derisively.  Hurt, Rachel leaves his apartment and goes to the top of the apartment building, where she phones him.  When he realises she means to commit suicide, he races upstairs, only to see her leap to her death.  After one of his patients taunts him over this rumor, Travis reacts violently and is put on leave, though he angrily quits instead. Grace, a young woman, hands out pamphlets on a train and invites Travis to a support group.  Though dismissive, Travis takes one of her pamphlets.  After drinking heavily and becoming depressed over his life, Travis attends the meeting.  Travis is disgusted when the group's leader, Father Jay, a military veteran and former drug addict, forces a young member, Marcus, to confront difficult personal issues in public.  As Travis leaves, Grace urges him to seek the group's support.  After a suicide attempt in which he overdoses on pills, Travis calls the group before slipping into unconsciousness.  Father Jay, Grace, and another member, Tom, arrive and induce vomiting, saving his life.

Travis
