This is something that's been lying in plain sight for so long, yet it completely went past me somehow. Another curious part is how the BiBG ended, suspiciously mid-way and with the death of our Tav character. What if this 'YOU DIED' ending is not the only one? In BiBG, there were clearly more days for us to investigate, as shown on the time scale at the bottom.
It is clear that detective Tav and TDU share a backstory and there is a possibility Tav is not as blank as it seems. A 'canonical' version of avatar Tav could also be a small possibility.
Could Tav be present in the game if you start your game as an Origin character or a TDU?
Well I don't think we create an extra character if we play the dark urge...other than the guardian but that's something else entirely. As for BiBG mentioning Tav, I don't think it's much deeper than an easter egg. Swen also recently encouraged people not to play Dark Urge first but at least for most other games people typically only play the game once. Even if far fewer people drop BG3 that fast I'd still expect Swen to strongly urge playing the Dark Urge first if this was indeed their idea for overall canon.
