Ackward yes, given that he was/is involved with her sister. However, looking back at their interactions in Season 1, I'd've been only slightly less surprised if the season had ended with Artemis and Will getting together rather than Artemis and Wally.
I know the Paula Brooks version (who is Artemis' mother) will be appearing but I didn't hear anything about Artemis herself being featured. That would be nice if so. I'd also hope she and Jade are sisters there like in Young Justice.
