Charles is about to wheel himself through that smoky doorway, personal safety be damned, when Sean comes crawling out, coughing and choking.

"Raven!" Charles calls for his sister's attention, taking Scott from her so that she can check Sean over. Thankfully, the boy seems fine aside from a great deal of coughing.

"Hank and Alex..." Sean tries to tell them, and Charles nods his understanding. Fingers to his temple - something he's not needed to do for a while - he tries with all his might to pick up on the others trapped inside the burning lab.

And still, nothing.
