In Venera, Silco attempted to do most takedowns stealthily, either in their homes or otherwise. He stalked his targets subtly, or using his invisibility powers, which ensured that he was pretty much not identified around the city for the most part. If he was watching targets, or talking to NPCs, he attempted to get information without identifying himself as an Aion -- and as always, he keeps his shard covered by his clothing.

HOWEVER, in his thread with Eustace, he did take the target down on a relatively deserted part of the street, however he and Eustace did get into a fight with the target and his bodyguard. There was little power usage, and they took care of them quickly, but there was a bit of a street brawl going on down there, which may have been a bit more easily identified than his other attempts to apprehend the targets.
