Why We Thought He Was "A":
- The fact that Holbrook is somehow involved with Ali and CeCe makes him a very plausible suspect.
- He seems to be around the same age as Ezra, which means he'd tie into all the "Board Shorts" drama pretty easily.
- His position in the police force affords him tons of opportunities to fudge evidence, have access to secret files, and even conduct dirty, malicious business without gaining much notice.
Why We Figured He Wasn't "A":
- Given the fact that Holbrook is a pretty late addition to the PLL family, he's probably pretty far down on the list of probable culprits.
- Holbrook comes into play only after the murder of Detective Wilden.
- We haven't seen any established prior connection to any of the girls (yet), so pinning a motive on Holbrook would be hard.
