We've all seen it.
We all know it.
And if anyone asks, we all know what it stands for.
Of course, it stands for Superman..
However, in the HBO show Krypton, we see Seg-El (Grandfather), Charys-El (Great Grandmother) and Val-El (Great Great Grandfather) wears the same family crest on their chest,
before they are striped of name, rank and house, and the House of El, no longer exists (microscopic spoiler, as it's the first scene of S1E1).
So, if since the Crest originates from Krypton AND (as we see on their computer pads) they don't use letters that even remotely resembles Latin letters, what the #{^*#^}#{ does the S mean?
Does it say "El" in Krypton language?
Is it just a nice picture?
