BtVS Questions

[shipperx]

A little fanfic research  because I'm drawing a blank.

*  What is the episode where Dawn finds out that she is the Key?
*  Is the episode where Buffy takes Dawn's hand and says "It's Summer's blood"   Forever?
*  What is the episode where Buffy says that Dawn is made out of her?  The Gift?  Weight of the World?  I've forgotten.

ETA: Asked and answered.  Thanks y'all!  Looks like I'm rewatching Blood Ties tonight (which is cool because there has been nothing on tv lately)
