Okay, so, Callie has been IMing with 'AJ' through the Fost and Found website. He won't tell her where he is, but they agree to meet at a cafe. However, while she waiting, she runs into her old boss from the drop in center. He suggests they do something together with Fost and Found (hello, you fired her). Callie hurries away, desperate to find AJ, but to no avail.
Later, he ends up calling Callie, and mentions that it's long distance. Which means, whoever she's been IMing with isn't AJ (Mariana traced the IP address to San Diego). When she confronts him about it, he goes off line. And we see that it's Jack. Jude super annoying new friend. He's been playing XBox and sleeping in the mom's bed. But he's weird and annoying. Either way, I have no idea what he might get from his. I cannot even begin to guess what his motivation for doing this might be.
Anyway, Callie tells Stef about where AJ might be, and she and Mike head down there to arrest Ty. AJ ends up in handcuffs as well. Callie is not happy and wishes she's never told Stef. However, Stef tells her that she told AJ to keep his mouth shut and he probably won't get charge with anything. I hope this means that he's back with Mike in the coming days. I'm quite enjoying him as a character.
Brandon and Mat are busy trying to write a Shakespearean rock opera for their senior project. Apparently, Mat has a delightful voice which makes him Romeo. But they need a Juliet and Mat suggests Brandon's ex, Talya (you know, the one I completely forget existed). Brandon refuses and claims they have to hold auditions. But, when Mariana auditions, and she's awesome, we stuck with which ex girlfriend do we need to spend our time with. And Mariana (who just found out she lost the election to Lexi) seems to win out.
Elsewhere, Nick is getting into Jesus's head about knowing who his biological father is. With some information that he picked up from his cousin, they head over to a construction site and Jesus just wanders around asking about a guy name Gabriel. When he's pointed out out him, he just tells him he was hired to work with him. He has no idea if this guy his is dad. But, we all just supposed to go with it? I mean, it seems like a pretty high likelihood given the information we have, but still. Also, why did Ana lie and say she had no idea who he is? How do her parents know who he is if she doesn't? Interesting. Maybe she thinks she's protecting the twins somehow?
Lena finally makes the decision to get a double mastectomy based on the results of her test that claim she most likely will get cancer at some point in the future. So, we're being proactive about this. And she asks her mom to stay (which I like), but mom tells boyfriend to head off on an adventure and come back later (which I also like).
