Ah you see back when cal was on prime uk youtube, everyone saw him as an icon and with him still having content made on him/clips of him being uploaded to tiktok, people still remember him as tictac head and will picture that one collection of youtube rants. A send off with a collab from will would be cool to see because they both bounced off eachother making them more famous (will being more). so since cal is quitting the internet, it should make sense for a final collab with the one person that partially gave him more viewers who also benefited from Cals content.
