"I swear he was this way! I'd recognise his voice anywhere!"

"I know Finn, but it's just that he could be anywhere and I didn't hear anything..."

"I know what I heard! Roger needs help and he's somewhere nearby..." Finn carried on running, closely pursued by Blue. He turned randomly whenever he reached a fork in the tunnels, desperately trying to find his brother. Blue followed him, panting and throwing bits of cookie behind her whenever she could.

They carried on running until Finn finally gave up. Underneath his helmet he knew his face was probably wet with tears, but he wasn't going to show his distress to Blue.

"I'm sure if you heard him, he must be nearby." She said kindly, sitting down next to him on the cold stone floor. "I know he is." Finn responded determinedly. He had definitely heard Roger shouting angrily; and then crying out in shock. Or in pain. He wasn't sure.

"Look." Said Blue. "Running around like headless chickens isn't going to get us any closer to..." She was cut off by a strange echoey noise from somewhere within the cave.

Finn leapt up. "That's it! That's Roger!" Before setting off running towards the sound. Blue sighed, got up and gave chase.

They ran towards the noise, Finn leading the way. He seemed to have much better hearing than Blue who couldn't really make out the faint noises that told him where to go. Suddenly he stopped so unexpectedly that Blue tripped over his foot and landed in a heap on the floor.

Finn helped her up. She started to groan but he put an urgent finger to his lips to quieten her. Blue strained her ears and could soon make out a faint snuffling noise from around the corner. It was followed by a lower sound and the faint clanging of metal on rock getting closer and closer... and then... silence.

Finn motioned to Blue, miming drawing their swords and attacking. Slowly, he unsheathed his weapon. Blue gazed at it in amazement. For such a brutal tool it was astonishingly beautiful. And her favourite colour, pastel blue.

She pulled her sword out too, careful not to make a sound. Whatever was in the cave with them, it was just around the corner.

She glanced at Finn who was advancing steadily towards the corner, helmet covering his face. He beckoned her and raised his his hand, holding up five fingers. Blue slid her own helmet's visor over her eyes just as Finn pulled down one of his fingers. Four.

Three.

Two.

One...

They charged around the corner, Finn in the lead. He swung his sword down viciously and it clanged against a piece of metal. There was a shout from Finn, another clang; and then Finn was lying on the floor groaning.

Blue stopped and stared at Finn blankly, not knowing what to do. She pulled out her marshmallow coloured sword just as an armoured figure rounded the corner, also staring at Finn who was lying on the floor.

The speaker tied around the figure's waist gave an exasperated sigh. "What the hell do you think you're doing?"
