Kate visit Claire in the hole, tells her about Aaron

Back at the temple, as Kate is trying to find Claire, she is stopped by Lennon who wants to know Sawyer and Jin are. He then takes her to "the hole" that Claire is in. Claire is singing the song "Catch a Falling Star," which was a big part of her and Aaron's childhood.

Kate tells Claire that she took Aaron off of the island and says that she came back to rescue Claire so she could be reunited with him. Claire looks extremely pissed, but then shares a creepy smile and says "I'm not the one that needs to be rescued, Kate." Lennon and two others pull Kate away before she can speak anymore.

Was Claire referring to the pending carnage of the smoke monster/Locke with her ominous question, her plans to kill Kate or something else altogether? Either way, it was quite creepy.
