Hail!
If you're wondering if Medea is always on, the answer is clearly, unquestionably, undoubtedly, definitely yes. Medea is always "on". The woman clearly has issues and we'll be exploring why in the next comic. The Starbolts often referred to her as their "Rita Repulsa" from Power Rangers. However, there's more to her than meets the eye. Is she more than just a very sultry void witch? Yes. Of course she is. I wouldn't write a character like this unless there was a valid reason for her behavior. You might want to get tissues, though. You aren't prepared for the feels that are coming soon.
At least she seems to be making amends for her past misdeeds. She offered to help Marcus with no strings attached. She changed Tanis back to normal after being transformed into a humanoid bug-man in Starbolts #195. The witch has been performing some extraordinary acts of kindness as of late. Trust me when I say that the Starbolts are a bit cautious and probably will keep her at arm's length.
Still, how awkward was it to have a former villain embrace Crystal RIGHT after commenting on her appearance. She sensed she was a void witch. But, that doesn't make her comments or actions okay. I foresee her butting heads with Cece when she comes to Earth. Cece is a more reserved void witch. Medea is not. There's gonna be some drama coming with those two. At least she's willing to help Marcus. However, there may be a method to her madness.
Stay tuned!
