The memorial date thing is just a misunderstanding... nothing more.

Bad Weather is making this such a thing, when it really isn't. It really seems like Lisa just mispoke when she called Meredith (or was lumping the memorial on Monday with Meredith's very real emotions 24 hours later) and wasn't trying to expose her as a liar. I wish Whitney and Heather would get a storyline of their own instead of always trying to investigate other people's drama.
