Sombra snorted and finally stepped away from the guard, satisfied that he'd managed to ruffle the pony. Picking one of the cushions at the table, he sat down, one elbow on the table's edge as he partly faced the unnamed pony. His expression, as sour as ever, but a glitter of amusement was in his red eyes. It seemed he'd found himself an easy target to torment for his own entertainment, something to do to assuage the boredom.
"Like what?" Sombra asked, a dark brow arching questioningly. The following admittance after the guard's statement drew a low chuckle out of the umbrum and he nodded, as if he'd been expecting it. "Of course it would get boring. You have nothing to do in this castle except to stand around and try ever so vainly to look pretty. I can't imagine that armor does any good, unless its just gold plated. Do you ever do any proper training exercises? Sparring? Anything that might help you learn worthwhile skills that you'd need as a soldier, or is it all wasted on.. standing around?"
He was trying to ruffle the pegasus's feathers, verbally of course, and however obvious it might be hardly mattered to somepony as antagonistic as Sombra was. He wanted to see how far he could push the pony, and just for his own entertainment. "I highly doubt the princesses would give you any commands, not when everything is always so peaceful and quiet around here. Not unless its to shine their shoes or.. perhaps on occasion, throw some troublemaker out of the castle at their behest." A smirk flashed across the former tyrant's face, as if anticipating any possible quips that'd involve just that- that he was just that troublemaker.
