Ah yes, I remember that scene. He was talking to Carrie Delgado in that episode.
Speed: He's some kind of forensic junkie.
Delgado: Yeah there are a lot of those going around these days.
Speed: Yeah but who grows up wanting to be a criminalist?
Delgado: *looks down at table*
Speed: You're kidding.
Delgado: Hey I grew up watching Quincy, I mean you didn't?
Speed: This job, it's a paycheck. It's not my life.
*sigh* Come on Speedy. You know it's not just a paycheck or you wouldn't have wanted to be a cop. People don't just get up one day and say "I think I'll do this super dangerous job and almost die every week because I want that new plasma screen for the living room."
I as well, wanted to hug the screen when Speed was being all brotherly to Wally.
It was such a tender and cute moment. I think what Wally needed was someone like Speed. I mean, you can tell Wally didn't have friends or people who could support him socially. Speed had that secret annoyance toward Wally, but he's a very patient person which was what - I think - created so many great scenes between them.
