A drawing of two stick figures looking at their phones, texting, with the messages they're sending floating above their heads, which consists of repeating letter A with various accents above and below. Above the drawing is a table mapping letters of the alphabet to variations of the letter A with these different accents. Using this table, we can decipher the text messages from the comic as "Hello" and "Hi". The text quoted in my post is written at the bottom of the comic.
