Just 3 more episodes left. I think they are playing the long game, trying to milk this as much as possible because there is a lot of unwanted stuff there. If they wanted to include all this stuff, they should have gone for a 23 episode season or something.
Episode 13 or the season finale is called Nightwing, so I guess the next three episodes are going to focus on Dick's transformation into nightwing. That would mean the season as a whole had no real direction and probably the deathstroke arc will extend into season 3. They should stop taking all these tangents and focus on the main story. While some episodes which took the focus away from the main story have been good (like the superboy one) most others have been meh, especially the last two. If they had 23 episodes, they could have used 4 episodes to show the transformation of Dick to Nightwing, but with just 13 episodes a season, you just can't dedicate 3,4 episodes to one character while almost completely ignoring the main villain
