Lahabrea is prepared to assist with dealing with the creature Byleth has caught, when movement out of the corner of his eye catches his attention. Fortunately it only takes a moment for him to turn enough to see that the movement is exactly what he expects they are, and with a grumbled snarl that sounds like it might be a bitten-off swear were he anyone else, Lahabrea reaches for the chains that are his by rights. Chains that he wields with the expertise of long decades of use as the incoming intellect devourers find themselves meeting the same fate as any escaped concept within Pandaemonium. The chill bite of the chains of interment, set to hold them for as long as needs must.

That it is no trivial magic is not something Lahabrea acknowledges. Even here this remains to him, and though the chains will not kill their targets they will make it less like that either of them will fall prey to their would-be quarry.

"Have you any spell by which to silence them?"

If not, Lahabrea can surely manage. But far easier if he does not need to.
