I am feeling bad for Cat noir... Don't read further if you don't want spoilers for season 4 or 5. In this end of season 4 Hawkmoth kills Cat noir and takes his miraculous. Ladybug has to find Cat noir's miraculous to make Cat noir alive again and by that time it will be the end of season 5. When Cat noir is dead he is replaced with Jagged stone who gets another miraculous. All this happens after the reveal in the end of season 4. I feel really bad that Cat noir dies... This also means one whole season without Cat noir and his puns. 😿
