In a situation, some people will be talking about another character in a conversation, and then the specifically said character appears from out of nowhere with or without a word, reactions consist of shock, surprise, and a lot of screaming.
It could happen when they say "I wish so-and-so were here" or something along those lines, and they show up, invoking Big Damn Heroes. Other times, the character shows up when they are having an awkward conversation about them, which may or may not invoke Acting Unnatural. If the character shows up when they were thought to be dead it might invoke Not Now, We're Too Busy Crying over You, and something similar might happen when they were thought to be in any other way "gone."
In some cases, the character was missing and the others were about to look for them and they appeared on the scene, unfazed. The character may or may not say something along the lines of "Someone say my name?"
