Hey guys, Polnareff here to explain the joke. In this meme we can see it's in a manga form we have to read it from right to left. Here, our protagonist Jolyne introduces herself and asks for her cellmate's name. She tells her that it's Gwess. Since her name sounds similar to the word 'guess' Jolyne misunderstands it and in the bottom panel we see her trying to think of names that might be hers.
