S2, E7: Kalvin, a gay man with full-blown AIDS, confronts House in front of his home, demands that House figure out what’s causing his illness - besides HIV or AIDS - and collapses at his feet. When Kalvin claims that House assaulted him, Cuddy tells House to give Stacy the facts. House meets with Stacy at her home - armed with some unethically-garnered personal information about her - and he and Stacy share close quarters when he tries to help her exterminate a mouse from her attic, to the chagrin of her temporarily handicapped husband, Mark.
