Molly O'Brien is out of control

The eighteen-year-old girl (an older Molly O'Brien) is brought back to the station (Deep Space 9) with her parents (Miles and Keiko). Even if she is wary and totally unable to communicate at first, she eventually recognizes her parents and grows less suspicious. She however misses her "home" and Miles and Keiko decide to bring her into a holosuite to cheer her up. The idea proves to be a good one but eventually Quark interrupts, as a couple of Klingons have reserved the holosuite and refuse to have O'Brien pay for their time. Miles tries to tell Molly the bad news, but when she completely ignores him, he is forced to end the program. The planet disappears, and Molly is stunned to find herself now in the small, confined room but the confusion soon gives way to anger, and Molly leaves the holosuite in a feral rage, and starts to tear Quark's apart. After assaulting a few people, a Tarkalean approaches her to which she responds by stabbing him in the gut with a broken bottle. Just then Odo and his deputies arrive and stun Molly, but the damage is done. The Tarkalean survives but presses charges.
