Martha nodded at Jack when he told her to call Mickey, frowning a little at his words about Mickey looking pale and being tired. Of course that could be caused by the adaptation to this reality combined with everything that had happened not even five days ago.
She took off her phone and speed dialed Mickey's number. Suddenly a ringtone started somewhere in the hub. Her frown deepened as she realised that was Mickey's phone ringtone. Looking briefly at Jack and the Doctor, and still with her own phone pressed against her ear, she started walking towards where the ringtone seemed to come from. 'The medical room' she thought to herself while approaching the set of stairs. It was still difficult for her to go in there without being immediately reminded of Owen, who wouldn't be there anymore. But those thoughts quickly vanished from her mind at the sight in the medical room. Mickey was sprawled on the floor next to the gurney.
"Mickey!" she cried out, going down the stairs quickly and kneeling before the unconscious man. She started taking his vitals and trying to figure out what was wrong with him.
