Well now you know that the crystal on the LEFT is sending electricty to the one on the right, thereby implying its the smart one....Can Chenjesu really discharge electricity?
"Unlike most other sentients, the crystalline Chenjesu are photo/chemovores existing on electric energy and have neither natural predators nor need for prey. Another distinguishing feature is the electromagnetic energy fields that they naturally produce, which create the characteristic Chenjesu crackling noise from minor corona discharges. However, when experiencing strong emotions, Chenjesu have been known to cause visible and audible electrical breakdowns in air, which often interfere with nearby electronics."
