I have to keep reminding myself of that, because, if you never read them, Gotham Knights is gold. There's a lot batfam character and relationships studies — an understatement — but if I have to be honest with you, the main draw is often the Dick-and-Tim sideshow of absolutely ridiculous, sometimes wordless banter.
I was going to say that although Tim during the whole "Bruce's not dead" Red Robin era (not the more recent insanity) is perhaps the archetypal expression of what I think he can be, I keep this Tim in my heart, because he's an earnest dork with a goofy sense of humor and I miss that.
But. While writing a bit more about Tim's search for Bruce (spoiler alert: Bruce wasn't dead), I suddenly realized something. Remember that awesome/awful birthday gift from Bruce in the form of a fake message from the future that made Tim question the sanity and morals of everybody he loved as a first step in the next stage of his training in detection? Tim's Bruce's not dead realization was very much close to that: a fragment of information out of time (in this case, paintings from the past) that he observed and deduced from in a way very few other people would've, regardless of their smarts, partly because Tim's a natural at this, and partly because Bruce helped him train in that way.
I don't know what I find more pleasing, the fact that what was arguably Tim's second legendary feat of detection (the first being of course figuring out Batman's identity) was so similar to that first lesson, or the irony that what he figured out was that the guy who had mocked him during for having bought the idea of time travel was indeed lost in time.
I don't think it was meant as a deliberate reference, but if it was, kudos.
