I found that Alice also proved to be an interesting plot device that potentially threatened the relationship between Sam and Mikaela. As someone who avoided spoilers before seeing the movie and had no idea what Alice was, I honestly thought she was some girl trying to shoehorn in on Sam in order to strain his relationship with Mikaela. At first I thought that this would be a really lame distraction away from the central tale of the Transformers, but then she turned out to be a Decepticon and suddenly everything made sense and she changed from lame to cool in my book. She also allowed for a comedic moment in the library scene with the argument between Sam and Mikaela (the "time out," diesel-flavoured kiss etc.).
