harry potter - Do you need to erase the memory of watching a memory in a Pensieve?

You remove your memory from your brain to store in a Pensieve (as Snape or Dumbledore did).

Then, you re-watch the memory (e.g. as Dumbledore re-watched his memories of Voldemort's investigations with Harry) in the Pensieve.

Does that mean that you now re-created the memory in your brain (because you remember watching it) and thus you'll need to extract/erase it from your brain again if you don't wish to keep it there for security/capacity reasons (which was why you stored it in the Pensieve in the first place?

Canon answers only please.

the lord of the rings - Why is Gimli allowed to travel to Valinor?

Gimli was allowed to go to Valinor despite not being a ring bearer. Is this explained in detail or just with the one line "for his love for Galadriel"? Answer There's not much detail about this aside from what's said in Appendix A to Return of the King: We have heard tell that Legolas took Gimli Glóin's son with him because of their great friendship, greater than any that has been between Elf and Dwarf. If this is true, then it is strange indeed: that a Dwarf should be willing to leave Middle-earth for any love, or that the Eldar should receive him, or that the Lords of the West should permit it. But it is said that Gimli went also out of desire to see again the beauty of Galadriel; and it may be that she, being mighty among the Eldar, obtained this grace for him. More cannot be said of this matter. And Appendix B: Then Legolas built a grey ship in Ithilien, and sailed down Anduin and so over Sea; and with him, it is said, went Gimli the Dwarf . And when that sh

Why didn't The Doctor or Clara recognize Missy right away?

So after it was established that Missy is actually both the Master, and the "woman in the shop" who gave Clara the TARDIS number... ...why didn't The Doctor or Clara recognize her right away? I remember the Tenth Doctor in The Sound of Drums stating that Timelords had a way of recognizing other Timelords no matter if they had regenerated. And Clara should have recognized her as well... I'm hoping for a better explanation than "Moffat screwed up", and that I actually missed something after two watchthroughs of the episode. Answer There seems to be a lot of in-canon uncertainty as to the extent to which Time Lords can recognise one another which far pre-dates Moffat's tenure. From the Time Lords page on Wikipedia : Whether or not Time Lords can recognise each other across regenerations is not made entirely clear: In The War Games, the War Chief recognises the Second Doctor despite his regeneration and it is implied that the Doctor knows him when they fir

What is the etymology of Doctor Who?

I recently decided to watch Doctor Who, and started viewing the 2005 version. I have the first two episodes from the first season, and I can't help but wonder what is the etymology of the name "Doctor Who"? And why does the protagonist call himself "the Doctor" (or is it "the doctor")? Answer In the very first episode of Doctor Who (way back in 1963), the Doctor has a granddaughter going by the name "Susan Foreman", and the junkyard where the TARDIS is has the sign "I.M. Foreman". Barbara, who becomes one of the Doctor's companions, calls him "Doctor Foreman" (probably assuming that is his name given his relationship to Susan), and Ian (another early companion) does the same in the second episode, to which the Doctor says: Eh? Doctor who? What's he talking about? "Foreman" is most likely selected as a convenient surname for Susan to use because it happened to be on display near where the TARDIS landed.

warhammer40k - What evidence supposedly supports Tau as related to the Necrontyr?

I've heard of rumours saying that the Tau from Warhammer 40K are in fact the Necrontyr. Is there anything that supports this statement, in WH40K canon? I just found this, on 1d4 chan 1 : Helping Necrons? Or are they Necrontyr descendants? An often overlooked issue is that Tau have no warp signatures, just like Necrons, hate Warpspawns and Warp in general, just like Necrons, have the exact same skull shape,stature and short lives, and the overwhelming need for Technology and beam weapons, JUST LIKE NECRONS. GW may have planned a race that simply prepares a pacified, multiracial galaxy for Necrons to feast upon, supported by Ethereals that have a C'tan phase blade. Then there is a reference of "dark seed in east" by the Deceiver, so the tricky C'tan might give Tzeentch the finger in the JUST AS PLANNED competition. Or maybe GW just has so little creativity that they simply made a new civ conforming to an Old One's standards without knowing it. Is this the connec
