“I should have kept it a secret instead of asking everyone about him,” Clary said in
horror. “This is my fault. I should have warned Fell—”
“Might I point out,” said Magnus, “that you couldn’t find Fell, which is in fact why you
were asking people about him. Look, Madeleine—and you—just thought of Fell as someone who could help your mother. Not someone Valentine might be interested in beyond that. But there’s more to it. Valentine might not have known how to wake up your mother, but he seems to have known that what she did to put herself in that state had a connection to something he wanted very much. A particular spell book.”

Chapter 7: Where Angels Fear to Tread
Oh look, there are actual consequences for Clary of opening her mouth and telling everybody what her mission was. Colored me surprised!
However, this rings hollow to me for several reasons. 1 ) Anyone with a lick of sense could have told you that something bad was going to happen if she kept just spilling tea the way she was. 2) It was also common sense that people in The Clave were going to try to stop her because they are still Circle Members in The Clave. 3) Magnus Bane, in a fit of OOCness I haven’t seen in a while, is quick to reassure her that Clary was not at fault and she shouldn’t blame herself.
It’s really very clear that Clary is never going to be held accountable for any of her actions. They might have realized what Clary was here for on their own, but she didn’t help anyone by blabbing her mouth. Honestly, Clary could have clandestine went to the library or round about asked about Ragnor Fell’s whereabouts.
I also find the timing weird. If they figured it out on their own, why did it take them so long to go after Ragnor Fell? They could have killed him long before Clary got there, but this whole scene makes it feel that Ragnor was just murdered.
