The song that Dominique begins to sing is "I'm Always Chasing Rainbows" by Harry Carroll and Joseph McCarthy.
The original title for this episode was "Takeover".
While the title obviously refers to Dominique collapsing in mid-performance at La Mirage, it can also refer to what appears to be the breakdown of Blake and Krystle's marriage thanks to the mystery photographer. It can also allude to Alexis' plan to take down Dominique which is scuppered when Brady refuses to sell her his stock in Dominique's company, and to the ending of Steven and Claudia's marriage now that she has slept with Adam.
