Today's trope is Identical Stranger. Here is the link: https://tvtropes.org/pmwiki/pmwiki.php/Main/IdenticalStranger

They say that everybody has got a double somewhere. After all, the Earth has a human population of 7 billion; it would actually be stranger if no two people were at least vaguely similar in appearance. On the other hand, it's not as common in Real Life as it seems to be in media.

On television this is often utilized for comedy, by making them very different people personality-wise.

As far as tropes go, this is one of the more ludicrously implausible ones. Take the probability of an Identical Grandson, ramp it Up to Eleven, and we're sort of in the right ballpark. This trope has stuck around mainly because it's a fun Plot Device. Meeting your own grandfather requires you to be in a Time Travel scenario, whereas a stranger can be, well, anyone more or less. Still, expect groans from the audience if this trope forces both identical strangers onto the screen at the same time a little too often. It gets past our Willing Suspension of Disbelief largely because it seems less improbable in the abstract than when we're directly confronted with it.

TL,DR: Two unrelated characters look exactly alike.
