It's not the years, it's the mileage. Or maybe he had just had a rough night...
I was so busy yesterday, I missed Hal's Birthday.
Happy (belated) Birthday, Hal!!
Having Oliver, Jeff, and Dick would greatly alter the character dynamics on the team.
Kendra makes it less of a sausage feast.
Hal bouncing off Barry & Oliver would be fun. Having Dick on the team alters everyone's dynamic with Bruce, as Dick has most of Bruce's skill-set, but with the bonus of people-skills. Folks may actually turn to Dick instead of Bruce during stressful moments which would be funny.
I said it before, a team-up between Hal & Dick would be a very fun read. Why no one has thought to do it is beyond me. That is a bromance just waiting to happen. Plus, it would be funny if Bruce actually got jealous!
Well, there was this.
