Here's my theory, I think that after Dah stole the Telegraph SPACEship he flew to the Square Root planet and stole one of the 42go prototype shells but then he was caught and had no choice but to escape in to the Telegraph, then he went to the Coptic planet and put on the shell then he started collecting the letters that he needed to spell friends in Coptic because it was clear that the characters on the Morse code planet didn't like him. Edit: In Lola we can see the fragments of something which oddly resembles the Telegraph SPACEship but it's obviously destroyed, so maybe Dah didn't escape the Square Root planet untouched, maybe 35 chased after Dah after he stole the 42go prototype shell and destroyed his Telegraph and then Dah crashed into the Coptic planet but put on 42go prototype shell before landing so that he didn’t die and that's how he ended up there, also in Lola we see ⲉ go down an elevator to his lair. Now who else seems to have gone down an elevator? Oh right, Space in his Telegraph SPACEship, so I think after Dah crashed into the Coptic planet he used bits and pieces of the Telegraph and the elevator to make a lair to store the letters that he needs to spell friends in Coptic, something else is when Dah's jaw gets ripped off he sounds a lot like ⲉ and even says something like "EEeahheh", "Eahhhh" and "Eahh" which sounds like how ⲉ says his name, even if my theory isn't correct, it is still 100% confirmed that Dah is ⲉ.
The epic return of Morse Code Lore! with a new character, (space)! BTW, will Morse Code Lore have a Season 2 like all Lores do you do (not incluing Coptic Alphabet Lore)
0:00 *D E E T…* 0:01 *D A A A H H H..* 0:04 *daaahh dies* 0:05 *S L Æ A SH!* 0:23 oh no… 0:26 SPACE 0:28 *slæsh gets punched* 0:33 *D A A A H H H wakes up*
when space ripped dah's jaw, he looks like e from coptic alphabet lore, he probably stole his spaceship, then got into the number lore world and 42 fixed him into e from coptic alphabet lore but hey, THAT'S JUST A THEORY, A NUMBER LORE THEORY!
(theory) the real ei is the flower that was used to form the word ⲃⲁⲇⲉ (ride in Coptic) dah after breaking his jaw could only speak vowels so he used a SPACEship and flew away with @ (@ this is also a morse code symbol) he flew to 42 to steal from him the corps to which 42 was going to restore C, flying to the Coptic planet he decided to parody ei because he looked like him with 42's corps and could only pronounce vowel sounds.
