^^I believe Lucas was just a distraction in the plan to frame Ali for attacking Mona, a plan by Mona's army to bring Ali down once and for all.

But I agree, Lucas face expressions doesn't make him neither the killer nor innocent. People copes with grief and death in a lot of different ways. Just because he seemed sad, that doesn't mean that he couldn't be the killer and just because Ali seemed completely unaffected outside Mona's house that doesn't mean that she is the killer.

And in addition it's PLL, anything is possible...
