Where does “shock” come from?

I need to pause here because there's a problem with the chain provided. The chain shows: - English shag - Middle English schaggen - Proto-Germanic skukkōną - Proto-Germanic skaggiją - Proto-Indo-European (s)kek- - Proto-Indo-European (s)kek- (repeated) But the headword I'm asked to write about is **shock** (English), not **shag**. These are different words with different etymologies. The chain provided doesn't match the headword. Could you clarify: Should I write the etymology for **shag** using this chain, or do you have a different chain for **shock**?
