The whole Arty/Ice Jr. thing really depends on how they play Deathstroke, who is seems to be her mentor in the clip. If he doesn't want her to date so she doesn't want to be distracted, then she has a good excuse to not date him. If not, she may have to pretend to like him to keep up her cover.

Also, Red Arrow couldn't have been crushing on Artemis because he was programmed by her father to consider her a spy and try to isolate her. Right then, it would have been against his programming to have any feelings for her but suspicion and hostility, which would have negated any of that.

And before anyone points out that he was hostile to Jade, falling for her wasn't against his programming, just against his character as Roy. In fact, he only married her after finding out he wasn't actually Roy.
