But why LMP? She doesn't seem that connected to Michael anymore. Does Michael and Harvey just pull straws and say, okay so and so hasn't done anything much; it's their turn for attention. Lisa actually asked for silk sunflowers, not real, as they would "never die". To her the importance was the quantity and permanence. Maybe it's a reference to Michael saying on the big screen at the Memorial, "I'm alive and I'm here forever" as in his song "The Man". He is surrounded by a "very large empty space" which makes me think if she knows he's alive (she was at the staged funeral) he is in a remote island, or up in the air (MJair blimp). The flowers this guy sent will be wilted in about a week, and then it will be back to empty space. She said we need to "Keep" him surrounded. What kind of atmosphere is he in, that it can be dented? Sounds metal.
It also seems to me overall, that many of these stories and clues, are like they are playing the game "word association", where you say one word or name, and I'll say a related word/name that comes to my mind, then the next person says something related to what I said. It's fun and takes you all over the place in a whacky way, but everything is always related.
