I suspect Kevin is more concerned about his C.V. than his boss' welfare.

Panel 1: Alison and Kevin are still in the corridor outside the Server Room

Alison:

If you thought I was in danger, why didn't you just enter the room?

Panel 2:

Kevin:

As I said, the door won't open and... oh!

Panel 3:

Alison:

You didn't bring your security key card did you?

Kevin:

No.

Alison:

That would be why the door won't open.

Panel 4:

Alison:

As "rescues" go, I've seen better.

Kevin:

Will this be put in my employee evaluation?
