Liz looks across the cab at Neil, blinking once, seeming to look more curious than sympathetic... "sorry.  We got here as quick as we could..."  She sits back then, squirming half her weight into Vivian's lap... she never puts her whole weight on anyone.  And that's it... it's like it didn't happen then; she picks up on the facial and body language of the others and projects her mood to suit it.  To be good company... for the rest of the ride to the compound.
