Perhaps the bitterness all stemmed from that isolation, the only pup in a litter. He may have formed a bond with his siblings though sometimes there were of course moments where it seemed glaringly obvious he was simply the baby, never to share the relationship of litter mate with another. Scoprion hadn't ever done much to make him feel such a way in all honesty but maybe that was why this had stung more now.
Arguments would continue as Scorpion continued to bat away each comment that Soliloquy threw at him. An outsider would surely have to praise the older male for the patience and calm that he kept with the irate young male. A fight certainly wasn't what was needed nor was it really what either brother probably really wanted it certainly wasn't Soliloquy's aim anyway, not that he'd really had any goal beyond finding Scorpion in the first place and that had certainly been achieved.
Then suddenly a new topic would be brought to the conversation, Scorpion's tone almost daring Soliloquy to ask. He would pause for a second, the annoyance being suppressed and his curiosity piqued. What was his brother plotting? "What have you done?" He questioned, tone a little calmer now though certainly lending to the fact that he wasn't playing games, Soliloquy was sure Scorpion was up to something and he was fairly positive that he would want in on it all.
