I mean if you honestly think that Raphael would hurt Mama Lewis, I don’t know what to tell you. One of Raphael’s defining character traits is how much he loved his mother, and he has done nothing but help Simon since he turned, and Simon wouldn’t even be “alive” if it weren’t for Raphael saving him.
Like, yes, Raphael’s methods of helping are unconventional and not always morally sound, but at the end of the day, he was saying and doing what needed to be done to protect his clan and family, which he has stated multiple times, includes Simon, even after the betrayal. Raphael wouldn’t let harm come to Simon’s mom if he could do anything to stop it, and he certainly wouldn’t do it himself. And now Simon is going to be much more motivated to find Camille, which is great, because honestly, Mrs. Lewis, (like the entire clan) is in danger from Camille just because she is Simon’s mom, and Camille is not above killing mundanes for spite and fun.
But Raphael is.
So yeah, was this Raphael’s nicest moment? No. But it will take a lot more than that to ever make me doubt his character and I trust the Shadowhunters writers, they haven’t let me down yet on the Raphael and Saphael front.
