Sure, I'll try to explain his rationale since this seems pretty standard to me. I've played many hands with Alex, but never with DoD, and I don't know what the tableflow (past/recent history) of this table, but I doubt it matters.

It's 3 handed - and DoD raised and called a sb 3 bet - that pretty much leaves his hand range at *anything* right about now (or close to it). If I was Alex, I'd most definitely call turn (that and I'm a calling station) because the turn raise could have been anything from [range of hands of villian]:

1) Pure Bluff of any two cards putting a move
2) Picked up diamond draw from turn.
3) Picked up straight draw of any sort from turn (9T, QT, 69, etc)
4) Delayed bluff of any sort of draw from the flop (24, 26, etc)
5) A pair
6) Something better than a pair. Like two pair, pair+st8 draw, etc.

Given this range, against #6 Alex is drawing slim/dead, against #5 he likely has 3 outs, and against 1-4 he's either already winning or have 6 outs.

It's just not good to fold at the point of the turn raise, and also it's an easy check raise if he hits the river (and no, don't fold to a 3 bet).

Yes, call river on practically anything except maybe 6d, but even then I'd still call (not saying I'm right, just explaining rationale). If part of the rationale of calling turn is the guy may be on the draw, then you better darn call the river if the draw missed.

(or, Alex called cuz HE FELT LIKE IT. That's a perfectly reasonable explanation too).
