I don't know Queen, Paulo got a bit of sympathy from me there, and Nikki was an evil *****, which made me like them both even more, and what a horrible way to die. I think this episode had a LOT of easter eggs, ones that will take a rewatching or two to find. And about Penny, remember, she found the anamoly we think because of the explosion, which the Others claim is the reason no one will find the 'island' again, so she may be trying, but failing.
