Fiona knew Lachlan too well. She told him not to move, and so of course his first instinct was to twist around and see what had caused the sudden change in her tone of voice. It had been tense before, and Lachlan had followed Fiona’s directive as he knew what was on the line and why she was so serious. Now though, he did not know why she was was still so strained, when they should all be jubilant that their mission had succeeded.
Logic dictated that he had been hurt, and more badly than the curiously numb feeling in his back would have him believe. Fiona would not have concerned herself with a scraped knee or other minor injury that would not impede their escape, but it was only her bracing hand on his shoulder that stopped him from moving anyway.
The victorious grin on Lachlan’s lips dimmed when Fiona laid the situation out for him, but it didn't disappear completely. Yes, he was hurt, but one of the sentries ran back and confirmed that the tracks were completely blown. It wasn't all for nothing then.
“You heard her, go.” Lachlan echoed Fiona’s sentiment, waving the other three off. There was no sense in them all risking capture, and it would be easier for two people to slip away undetected than it would be for five.
Had he thought there was a likelihood that he would not get away at all, he would have waved Fiona off too. There was no need for the captain to go down with a sinking ship.
Lachlan took in a deep breath and steeled himself for the pain that was to follow. “Do it now. Don't toss the shrapnel, no need for them to know one of us got hurt,” he said, speaking more for the sake of it than because he thought Fiona might not think about leaving evidence behind.
