Bonnie is really starting to think this is the best dream. It seems like whenever they want something, they stumble on it. They want a way to celebrate Caroline's birthday? They literally stumble on a venue for birthdays with buttons for options. They lament about how Elena is not here to celebrate the day with them? Elena shows. She should probably be more suspicious, but she's still innocent enough and new to the supernatural that she's just gonna enjoy.

"Elena!" She grins, glancing over at Caroline and then heading to Elena's side, wrapping her arms around her in a tight hug. "It's Caroline's birthday!"

The three of them should always celebrate birthdays together. Nothing else makes sense.
