Born to be King

Loki was many things, but one of his little-known habits was his curiosity, or rather the fact that he acted on it without necessarily thinking about the consequences. Well, it was more that he did not care, to be honest. Loki is a scientist at heart, he likes to test things, so what could be better for a magical being like him than to have the Tesseract? Of course, he was going to experiment with it, what was Thor thinking?
Oh, yes... Thor did not know. It did not matter though. It was a detail.
Except when said detail led him to a Thor with TWO natural eyes, an adoptive father conveniently falling into a magical coma to let him deal with the shitty foreign policy – with an impending war, had he forgotten? – and a still-living mother who had always been too perceptive for her own good. Bloody witches.
What's more?
Oh, yeah, a biological father he apparently had not killed with his own hands yet.
...wonderful day in sight.
