Satoshi was taken aback by the situation that he was speechless for a few seconds. He didn't expect the Summoner to just disappear in front of him after being touched by the blue flames. After all, he believed that Dex's suggestion would work out for the better. Who would've thought that it would end in a way that he least expected. Slowly, he inhaled and exhaled to regain his composure before turning to Dex and asking him about the current situation.
"Care to explain what just happened, Dex?" He said in a calm tone. He didn't want to blame everything on Dex since Dex was the only one who instigated it. For all he knows, he was the one who listened to him and killed the Summoner.
