Oh, man, I'm sorry! I broke your vault!— Clem

Clem is a test subject in Vault 88 in 2287.


Clem arrives at the Vault eager and happy to help with anything that needs doing. He mentions his mother often and is not willing to blame her for anything. He is not very bright and is liable to blame himself for certain experiments "going wrong" until being reassured he did them just fine.

Depending on choices made during Power to the People, Clem can become an unwitting Buffout addict due to the Power Cycle, with the majority of his dialogue afterwards involving a request to use the Power Cycle, or a praise of the cycle.[1]
