Scapegrace and Torment

Hey ppl, if you read Playing With Fire, the part where they have to shoot the reflection, Scapegrace seems to feel abandoned when Torment doesn't save him from Skulduggery. i Can't give you the words cuz im at school but if you read those chapters it is kinda suspicious. after reading PWF for the millionth time, it only just struck me......Could Torment and Scapegrace be related?????? thoughts??
