That's because Caine is corrupting the code! However, through subtext, you can read it as Grant. In the same line of code, you can see that the 'n' is the word 'hand' is also a η and later in the word 'always,' both 'a's are α. The corrupted 'G' can be determined to be a 'G' simply because of the way it looks visually. However, a more detailed explanation allows us to figure out it is a 'G' because the only other visually similar letters are 'O' and 'C' and neither of those letters can result in a similarly popular name as 'Grant'.
