Both Lindy and Leti have a mark on their foreheads which appears to be 4 triangles pointing to one another
they aren't related. Neither one of their sons, Chrono and Griffith respectfully, have this mark and Clyde, Chrono's Father does not appear to have this which rules it out as being genetic.
it also doesn't appear to be associated with their rank in the Dimensional Navy as Gil Graham does not have it and he too is an Admiral like them.
So why do they both have the same mark on their forehead? is there some meaning behind it?
1: the image of Lindy is from the first Movie which seems to have high quality artwork than the series so i am assuming that while Leti's appears as 4 dots i am assuming that it's supposed to be 4 triangles aswell
