I think so. Lekain's speech in 4-F-1 suggests that, to most people, the heron assassination thing is still a thing. (He treats like his admittance to Sanaki is based on the fact that they'll die soon anyway.) And that it's credible enough he'd do it again.


Lekain: And somehow, despite the extraordinary plans of great me, here you are
standing before my very eyes.

Sanaki: If Sephiran and I hadn't been freed... You were just waiting for your
chance to kill us? Just as you killed my grandmother.

Lekain: Out of respect for the imminently deceased, I'll be completely honest.
Yes, you assume correctly. Your assassination, and the plot to once again
frame the Serenes herons for it, was entirely my idea.

Sanaki: Yes... I thought as much.
