No. Trust me, we've all been over this before...
Parson could have caused the link to break by talking to Misty. That is what Wanda is upset about. Breaking the link can have grave consequences.
Sizemore explains it here in panels 7-10. From Panel 10: "Talking to them as individuals can break that spell, Parson" (bold added). This indicates that it is possible to talk to them as individuals without breaking the link. Parson's apology in the same panel indicates that Sizemore is aware of what happened with Misty.
The link did not break until Stanley ordered it.
