Jace paced back and forward across the worn patch in the carpet,

'Oh calm down, Jace, you're overreacting.'

'Overreacting? I am not overreacting,'

'Dude,'

Jace stopped and glared at Alec, who calmly returned his look from his armchair in front of the fire.

'You're overreacting.'

Jace growled, before resuming his pacing.

'But this is so… out of character for her!' he cried desperately,

'So she wanted a change. So what? It's not like Isabelle has never done it,' Alec replied, a mixture of amusement and exasperation in his voice,

'But Clary isn't Isabelle!'

'Alec, Jace, are you in there?' Clary's disembodied voice floated down the corridor,

Jace froze in his tracks, a terrified expression on his face,

'Dude, get over it - it's just a haircut.'
