Mona’s Secret Message Anagram for Charles or Rachel DiLaurentis?

Mona left the Liars a cryptic message in PLL “The Melody Lingers On” 5x23.  The Liars find a hidden card in Mona's room with the message “Chandelier’s rituals.  Sister launched lair.  A ruler’s list chained.”

Interestingly, those sentences are all anagrams for “Charles DiLaurentis”.  However, they are also anagrams for "Rachel S. DiLaurentis". 

PLL showrunner, Marlene King, retweeted this theory.

@PllFanLife @imarleneking it could also be Rachel's or Rachel DiLaurentis...

Do you think this anagram is a clue about the mysterious twin we’ve heard about?

Mona was always fond of secret messages and codes.  Remember when Mona created a secret way to communicate with Hanna in “Crazy” episode 3x07?  She told Hanna to take the first letter of each word to spell out a new word.  She used that to secretly give Hanna the message “Maya knew”.

What do you think Mona’s secret message means this time?
