[Umbrella Academy] Why not just knock on the door?

Minor spoilers for Season 2 follow. The title is cryptic to avoid spoilers.  
**Why did Diego and Five break in to Hargreeves' office in Season 2 of UA? Why not just knock on the door and say hi?**

In Season 2, Diego and Five decide they want to talk to Hargreeves, so they break into his office in the middle of the night. Hargreeves, understandably, is not happy with this, shenanigans and stabbings ensue.

But... *WHY?* At this point, they have no reason to mistrust him. In fact, they seem to be expecting an actual meeting (Five mentions being nervous just thinking about the prospect of meeting Hargreeves). So, why on earth are they breaking in?

I think given all the lies, half truths and manipulations that they all endured during the events of season 1 and their childhood, I'd say they had plenty of reason not to trust Hargreeves. Especially once they suspected that he was somehow involved in the Kennedy assassination plot.
