Tarkin will just straight up deny Sirejj trying to tell him anything I think.
Tarkin settled into that position for awhile, lying on his stomach for about ten minutes to scope out the area. He trailed a finger over a lump of melted soil--what interesting minerals these were--the chemical properties were like nothing he'd ever seen. They made charming jewelry, too. Senators often adorned themselves with rings and necklaces bearing gemstones from the Atoan mines. He could see why, now, studying the strange whorls made by the glasslike material.
Eventually Tarkin was satisfied that there were no traps, and he rose from his hiding place to stride down to the cathedral. He could see Sirejj already; the Zabrak looked ill at ease. Tarkin clasped his hands behind his back and tilted his chin, eyes flickering to the rubble and the empty mosaic space. It was still a bit disconcerting to see that area so bare. It had been dark with his son's blood the first time he'd seen it, but the elements had wiped away any evidence of Garoche's death.
