Dren was thankful for a little respite after such quick spell slinging, taking a moment to wipe his brow and slip his hand back over the ball of his cane, more appropriate for walking, as that's what they'd be doing. When they found the other survivor, Dren felt ready to spring up and help her... and then, much to his surprise, she dealt with the threat with little effort. His brows raised, impressed with her actions... this young lady was far tougher than she looked, he remarked in his head. 

The fellow's remark made him introspective for a moment, briefly glancing up at the brim of his top hat. Yes indeed, he bore a familiar of his own. And considering the intense strength the young lady, or Garnet, just showed, it was clear she had one too... in fact, now that attention had been brought to it, Dren could feel it... the pulse... a distinct heartbeat dissimilar from his own, but all the more missable without focusing on it... 

"Fascinating." he remarked, scratching his chin. "If there are three of us that can locate this pulse, we'll be able to locate the others with relative ease. Of course, getting to them will be our issue." He continued to say, keeping to the left side of the group for protection, turning over ideas in his head that now buzzed like a swarm of bees.
