He didn't completely betray Morgana though. He didn't kill her, and he must've known she would recover from that wound. Plus there was the part where he left Merlin for dead. He's clearly trying to worm his way into Arthur's inner circle, but it is for nefarious purposes. He let Morgana live for a reason. Perhaps because she presents a convenient external threat for Arthur to battle, so he'll fail to pay attention to what's happening right under his nose?

The one piece of the puzzle that *really* doesn't fit is that he's not trying to convince Merlin he's not a threat. He doesn't tell on Merlin, but he does nothing to soothe his obvious suspicions either. I have no doubt that he hates Merlin as least as much as Morgana hates Arthur, but why not kill him, or convince Merlin he's a changed man and then betray him?

One thing is very clear: Mordred is playing a much longer game than anyone else in the series. I'm looking forward to how it plays out.
