So far so good this is what we know

All three butterfly theories remain viable. Perhaps the butterfly symbolizes both Messmer and Melina, suggesting Melina's ability to transform into Messmer, similar to Marika's transformation into Radagon; alternatively, they could be brothers, explaining their shared trait of having their left eye closed and possessing reddish hair with gold eye color. Also they could be the mittle brother Malenia with MA , Melina or Messmer with ME and Miquella with MI.
