The previous episode seems to have started a new trend, starting with the crime before the team gets there.
I'm glad to see Angela's still working the widow case. I was curious how they would deal with the sheer volume of evidence when they couldn't spend several episodes to address it. This is the smart way to do it, when they come back to the case, all the evidence will be processed and they will focus only on what is relevant.
Booth's loyalty to Riley blinds him to his obsession, so full of hate and frustration that Booth should never have let him be involved in the case. For the same reason that surgeons can't operate on family. Riley could have completely messed up the case.
Not a completely original story, NCIS did a similar story but this was still done well and I liked it.
