Kate is doing pretty well in the Commonwealth all things considered. She's doing her best to help people in the wasteland, which is why she became general of the Minutemen and joined the railroad. She became besties with Piper, currently hangs out with Nick and recently put down Kellog and found out (with me) that the Enclave still exists.

Here's a few highlights :

Fresh out of the vault

About to meet the Minutemen (ft Dogmeat)

1st time in power armor (she will proceed to decimate a dozen of raiders and a Deathclaw in the following minutes)

In the Silver Shroud getup (ft her bestie Piper)

On a case with Nick
