Actually, it was the MASSIVE lame excuses. As for the PL lie I do believe his name had been suggested to her by ILE.
There has been one thing that I believe has not been stated enough here or in the media. The language barriers. It has been shown on a number of occassions that misunderstandings can happen between individuals that speak the same language let alone trying to relay information between ones that speak different ones.
During AK's testimony she finally did switch to Italian as it appeared something was being lost in the translation
Of course, by the time AK testified, she had been living in an Italian prison and speaking Italian for over a year.
I know I sound like Johnny-One-Note on this subject, but all of Mignini's theories of a 3-on-1 killing ignores the language difficulties the "3" must have had. This difficulty PLUS the lack of time the three had to make a plan is what most convinces me that AK and RS are innocent.
