The FBI team has been through a lot this season onBlindspot.
He doesnt fully trust her, and he feels betrayed, so hes using his authority to chastise her.
Jane notices a strange pattern in part of the puzzle Pattersons working to decode, but thats about it.

Those bombings were enacted by Lilly Terrace, whos still in prison, so this must be a copycat.
Whats the motivation for bombing the exact same places?
They dont have to wonder about motivations for too long.
The episode then flashes back two years.
Digging into the bombing case, they cant find any connection between the three victims.
It all seems so random.
That is, until Rich Dot Com is brought in from prison.
Weller thinks Rich is playing them, but Rich lays it all out.
There are a ton of negative ones, and Rich has noticed that they share similar syntactic qualities.
The team brings Lilly in, and things start to go off the rails.
Its real close to a coerced confession, but the team seems mostly okay with it.
Still, they need some sort of evidence to back it all up.
Thats when some evidence drops right on their doorstep.
Stuart has no idea what hes looking at, but Rich insists theyre the future.
He says he can rebuild the camera and maybe get some video from it.
Shes not there at the right time.
Her delivery is from two days before the bombing.
It says hes teaching high school chemistry, Rich says.
Anyone else getting aWalter White vibe?
The team is ready to roll out and take down Albert, but Weitz changes that plan.
Instead, he orders a DOD drone strike that blows the whole place up.
Weller and Jane seem to know this too.
That call is from Madelines buddy Dominic Masters, the one who helped expose Zapatas undercover operation.
He knows what Weitz did, and he promises that this isnt over.
At the same time, Patterson figures out the pattern in Shepherds puzzle.
It corresponds to a 3D-printing code, which prints out a key.
I dont know what its for, though, she says.
