I never quite understood the opinion that new52 Tim was absolutely different to pre-flashpoint Red Robin Tim. I personally never felt he was. Granted New52 Tim was much more exaggerated, (like RR Tim bumped up to 11) I'm not claiming that they are the exact same, but that 'humble personality, and quiet awkwardness' was Tim from his earlier Robin days. Red Robin Tim was much more confident in his abilities and wouldn't hesitate to rub his intelligence and wit in an enemies face if he had the upper hand, he was still undervaluing his own life and his place among the family at times, but not his capabilities. Hell this cockiness at times would mean that he would talk down to others, as he did with Steph.
This less uplifting and more cocky exterior was of course more naturally felt during the events of Tims life in pre52 when he lost his family and friends and even when he lost Robin, although I wasn't fond of the direction his character was going it did feel very natural and was still interesting and engaging as such, regardless of whether I found him likable anymore or not. So, not being too fond of Red Robin myself, when the new52 reboot came, I was hoping that his character would be taken back to his more 'Robin' personality, and as we all know it wasn't, the Red Robin personality became even stronger and even more unlikable. I thought Tynion would regress him back, being the 90s lover and such, but sadly thats not the case. Rebirth Tim isn't AS bad as new52 Tim, but he is almost just as condescending as Red Robin Tim. :/
