In this exclusive clip from tonight's mid-season finale for Person of Interest, we are treated to a classic "birth of a hacker" scene from computer mastermind Finch's past. We've also got the scene in the form of a comic book from DC Entertainment — also an io9 exclusive.

I love watching young Finch as his hacker instincts awaken. When his father can't figure out what's wrong with his car engine, Finch takes the entire thing apart in order to find the broken part. "You're not supposed to take things apart like that," his dad warns gently. "Well, if they don't want you to get inside, they ought to build it better," little Finch retorts.

Spoken like a true hacker-to-be. We can't wait to see tonight's episode!
