question:
The Fifty Shades trilogy was developed from a Twilight fan fiction series originally titled Master of the Universe and published episodically on fan-fiction websites under the pen name ``Snowqueen's Icedragon''. The piece featured characters named after Stephenie Meyer's characters in Twilight, Edward Cullen and Bella Swan. After comments concerning the sexual nature of the material, James removed the story from the fan-fiction websites and published it on her own website, FiftyShades.com. Later she rewrote Master of the Universe as an original piece, with the principal characters renamed Christian Grey and Anastasia Steele and removed it from her website before publication. Meyer commented on the series, saying ``that's really not my genre, not my thing... Good on her--she's doing well. That's great!''

is fifty shades of grey fanfiction of twilight?


question:
Dr. Bailey is in labor, and without her husband Tucker Jones by her side, she refuses to push so she can give birth. George works with Addison to convince Bailey to have the baby. He finally gets through to Bailey by giving her the motivation that she needs, and ultimately he holds her while she delivers the baby. Izzie and Alex have sex again. Chief Richard Webber is under a lot of stress from everything that's been going on, and it is believed that he is having a heart attack, which lures his wife Adele to the hospita(anxiety attack)). Dr. Bailey's husband goes into cardiac arrest. Meredith finally removes the explosive from the patient, and Dylan, the leader of the bomb squad, carries it away. Meredith steps out of the operating room into the hallway, curiously watching Dylan walk away with the explosive, and at that moment, the bomb explodes, killing Dylan and a second bomb squad member. Meredith is knocked unconscious by the explosion. There is a revival of the ``shower scene'' from the first part, but with a more serious tone: the fully clothed Izzie and Cristina wash blood off of a stunned Meredith as George looks on. Dr. Bailey's husband and the man who had the explosive embedded in his body both survive. At the end of the episode, Preston and Derek become friends, overcoming their initial rivalry in the series beginning, and call each other by their first names. Cristina says ``I love you, too'' to a sleeping Preston. Derek comes to visit Meredith and says, ``You almost died today,'' and Meredith tells him that she can't remember their last kiss. Derek recalls the kiss for her, telling her that she ``smelled like some kind of flower,'' which Meredith says was lavender, and then he leaves.
answer:
did the bomb really go off in grey's anatomy?


question:
Together with the Saint Lawrence Seaway, the Waterway allows both ocean-going vessels and the ore and coal-bearing lake freighters to travel from the system's saltwater outlet to its far interior. The Waterway has larger locks and deeper drafts than the lower Seaway, limiting large freighters to the four lakes upstream of the Welland Canal and Lake Ontario, and similarly restricting passage beyond the canal by larger ocean vessels. The two waterways are often jointly and simply referred to as the ``St. Lawrence Seaway'', since the Great Lakes, together with the St. Lawrence River, comprise a single navigable body of freshwater linking the Atlantic Ocean to the continental interior.
answer:

do the great lakes connected to the ocean?
