I think one of the creators mentioned Pumyra becoming a re-occurring character. Plus if the Thundercats are going to infiltrate Plun-Darr they are going to need a guide that's been there before and that's Pumyra otherwise they will be flying blind. I also would think it would be hilarious if Lion-O starts flirting with Pumyra and thinks her affections are genuine only for her to go after Bengali if he were to actually show up. Lion-O being continually shunned romantically would be the perfect running joke for this show. Like, let's torture and humiliate Lion-O just a little more. And let's say he were to meet one of the Amazon warriors who also knows sight beyond sight, have her shoot him down as well . Or they could just advance the Pumyra angle by saying she actually does like Lion-O but doesn't think she should pursue the king. But whatever, come what may.
