I was just doing some procrastinating by reading up on some halo lore, and the wiki states that Kat was "indirectly mentioned" in Halo 5.
I don't recall this, and it doesn't give any explanation; so does anyone know what this mention is?
Unless they consider having her armour in the Memories of Reach update indirect, I have no idea what this was.

Probably in an armor description somewhere.
