I really get me extra-overwhelmed, I mean this changes completely how you see Miss Martian, at start she's just looks SO cheesy, now you see how DEEP she really is; this episode really make me believe she can't be the mole, but can become one, not probably but can. Also make me feel sorry about her.
Robin issues with leadership are bad, trauma stills there sirs. and it makes he really don't like leader things.
Now we know that Garfield will be Beast Boy thanks to: Miss Martian blood + little monkey bite = BOOOM coming soon a lil' Beast Boy (/ ^3^ \)
This also confirms something to me, little kids looks extremely cute on the series.
