Oh hey, I actually found it again. Here is their, um, reasoning. (I'm copying the post in full.)

So I’m rewatching some of the Agent’s of SHIELD episodes and the more I watch it, the more I want Loki and Phil to see each other again, and I just want them to apologize to each other.

And not Loki for stabbing him, because it’s not in his nature, but because he knows how Coulson feels with wanting to die.

But I want Coulson to apologize, apologize and realize he feels like Loki a bit: he was lied to by his “parent”, SHIELD about what happened to him in “Tahiti”. He wanted to die after he saw what he saw and now that he’s not dead, he’s prepared to fix Shield by ‘taking them down’.

Just like Loki. (read as: finding out he’s Jotun, trying to destroy the Frost Giants and then tried to kill self at the end of ‘Thor’ but then not dead so… his ‘fix’ is to rule earth in ‘Avengers’)

Different tactics and ways, but now he and Loki are so similar it’s not funny.

I want them to see each other again, just to see what they say because they both have to know: they are more alike than they know.

My brain still can't follow their particular logic.
