Thor | Loki
See. This was exactly why Thor didn't stop to formulate plans. Everything just got lost in translation. Actions spoke louder and what he wanted to do was just go down and fry the fuck out of whatever was down there that apparently grew offended enough at the sound of one's voice that it felt compelled to attack and rip the speaker to shreds. Thor thought that was rather extreme, but if that was the case then that's what they were dealing with. And if there were people to be saved, then so be it.
Loki's response had Thor all but ripping his hair out -- which was growing steadily back because he didn't know how to cut it. He had to physically restrain himself from groaning/growling in frustration because Loki definitely knew what he was saying but maybe he didn't and maybe it wasn't the best plan. He waved his hands back and forth as if to erase that plan, and came up with a new one.
He pointed at Loki, and didn't quite know how to mime what he was trying to say. He pointed at Loki again, then counted on his fingers as if to indicate multiples -- for Loki to copy himself down on the ground to fool the creatures. Then he pointed to himself and made the lightning spark between his fingers again, and of course pointed to Loki again and did the stabby motion/face combo again.
