Continuity mistake: Near the beginning when Chris and Phoebe are talking in her office, the loose ends of her scarf switch from being in front of her to being over the back of her shoulders in almost every shot. (00:00:50)
Continuity mistake: When Chris tells Phoebe that searching for Jinny at the dig site may be a trap Chris is wearing a zipper hoodie, but in the next overhead shot just as Chris sees the hole containing bones Chris has on what looks like a leather jacket, and then it's back to the zip hoodie. This is odd, because it's not until later after Leo heals Chris, that we even see Chris in the leather jacket. (00:03:10)
Answer: That was a mistake in the series.
Also, the episode is called 'Babies First Demon' and this alone tells us that it's Wyatt's first time in the field (so to speak) and as the sisters say, they've done a good job of clearing up their own magical messes so far. Nobody really knows how advanced Wyatt's powers are, or will become. That's why the cleaners appear, to nip things in the bud. The Cleaners didn't want to chance that the sisters could clean Wyatt's magic up, just incase they couldn't. Therefore intervening themselves, just in case.
