User blog comment:AdmMiller/What's so great about Tali? And why do most dislike Miranda?/@comment-2036282-20100715133417

@ H-Man Havoc: I was awaiting answer for a long time, but I'm sure the discussion is worth it.

About maturity: I thought Quarians usually become teenagers(or I could call this age so) when they finally get out of a bubble, where they spend their childhood. But they become truly mature only after having completing their Pilgrimage and giving something to a captain of the ship they wish to join.

Secondly, Tali mentioned strict rules(I should have remembered this) about possible children. She claims that Admiralty Board oversees the birth of all children on the Migrant Fleet(this I remember correctly, I hope), and parents usually aren't allowed to have more than one because of lack of life space and resources(though this rule can be cancelled if there is a real danger of extinction). Maybe Rael'Zorah was planning something different(for example, find somebody who could make a good couple with Tali, another quarian, of course) from having his daughter engaged with Shepard.

Yes, the ships appear to be sterile and so on, but they are also extremely crowded. And it would be common fact if the daughter of the notorious admiral has sex. It is surprising that nobody tells Commander Shepard about it(if it is a secret for all strangers or non-quarians, then I surrender:P).

As for concealing, honestly, to me it looks odd. Tali never seems to hide something from Shepard, she tells Shepard everything he asks: about Pilgrimage, the Geth, Quarians' culture, about her family and her mother(this she could also prefer to conceal, but nevertheless she didn't). However, I won't say your point is impossible, I'd just say it is not very possible.

I think that's all for now. All of this is my IMHO.
