The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at the Trope Launch Pad.

The second... I don't see that as being anything trope related.
Still, are you sure this is the right forum to discuss that sort of thing? This is Lost And Found, not Ask The Tropers.
