User blog:XV DEaD ShOT xV/Why Lucy Appears Blue?

As we all know by now, Lucy was a triple agent from the beginning of the series. She was pretending to work for Abstergo, but was actually working for the Assassins. THEN, we find out she was pretending to work for the Assassins, but secretly working for the Templars. If any of you played AC1, 2, or BH, then you know that she appeared blue in Eagle Vision. Some people (includong myself) wonder why this is.

In the articles it says that it's because Desmond thought he could genuinely trust her, but I concur. They use Eagle Vision to find out if they can trust them. Could this be because he actually COULD trust her? Maybe the rest of the Assassins couldn't, but possibly she would never purposefully cause Desmond harm?

If there was already a discussion with a solid answer, link it with respect. I apologize for bringing this up again if there has already been a decision. If there has not been, please, leave your thoughts below.
