Blake's consistent. She's an introvert and has already shown hints that she's a friendly person once you get to know her way back in episode 3. We get to see it at full blast in episode 9-10.

Her mysterious aura is still there. She's just not showing it to blend with Team RWBY, who's currently dominated by lots of energy.
