Now I just need to know if the Adept and Troll have any thing visible that points to their Awakened status. Sometimes prejudice can be a beeyatch.
"Perceiving Magic" (p. 280) doesn't list Adept powers, and no Adept power lists any sort of visibile manifestation. So while its possible to notice, say, the casting of a manabolt, Adept powers can not be perceived in such a way.
Some of their feats can be deduced to be supernatural - it's pretty obvious if you're running along a wall that something is magical there,but being faster/stronger/tougher than a normal (meta)human can also be seen as such: "Whoa, this guy is quick, he might be an Adept!". However, that's pretty hard to distinguish from Augmentations giving you the same abilities.
However, Augmentations are actually a way to suspect someone is Awakened. Plenty of people have at least some minor cyberware, especially in the shadows. If you don't - well it's not a sure thing, but maybe you're awakened?
But long story short - being magically awakened doesn't alter you in any way that can be seen. If you aren't casting spells, wearing obvious foki etc., no one knows that you're capable of magic - which is actually a major reason for people who are afraid of mages and adepts.
