Troy may be gone, but “Community” has a replacement friend for Abed (Danny Pudi) coming right away. “Switched at Birth” star Katie Leclerc guest stars on “Analysis of Cork-Based Networking.”

If you ever wanted to know how to say “I detonated a mollusk” in American Sign Language, this is obviously the episode for you. It’s unfortunate for any budding friendship between Leclerc’s character and Abed that relationships are founded on more than crustacean violence.

So why is Abed wearing giant headphones that don’t allow him to hear anything? It seems that the young man is now obsessed with a book series (think “Game of Thrones”) and wants to avoid any spoilers.

The result is a possible match made in silent heaven.

“Community” airs Thursdays at 8 p.m. on NBC.
