Aatrox sound effects during his ultimate was found to contain backwards hidden messages, some from his voice lines but also a few knew lines. Tahm Kench lists Aatrox as a friend, and during his voice over calls him "Brother". Tahm Kench is the first confirmed "demon" in Rune Terra. Seeing as backwards heavy metal records were rumored to contain hidden messages, I wondered if Tahm Kench's audio did too.
