The TL12 device now has to communicate via it's own lights and functional emitters...at least until they find the "flat rock that talks".

Especially since the beings of TL12 probably had built in wired or wireless devices to communicate directly with the weapon. Heck, they might have let the weapons take control of their bodies for the duration of the combat if the beings weren't trained to fight.

An option that might work would be for the weapon to have a section like a touch screen or e-paper that it can display images on. Over time, the user notices that the weapon mimics written words that are nearby. If the user takes the time to try and teach the weapon, he finds a capable student. Of course, that assumes reading/writing.
