Sorry, you can't.
Bioware Heavily Implies Liara Should Be Your Canon Romance
There are multiple characters that you can romance, but not at the same time as another.
If you pursued and completed a romance with her in Mass Effect 2 there will be some conclusion. Yvonne Strahovski has been cast for Mass Effect 3 but not as squadmate. Miranda's role will probably be larger than Ash's Mass effect cameo appearence. Project director Casey Hudson said in an interview that he hopes she's okay. Miranda and Shepherd will have a romantic conclusion based on everything the Mass Effect team at Bioware has realeased. But you will not be able to start a romance with her in Mass effect 3. If you want to romance her do it Mass Effect. There will be a love triangle situation between Shepherd, Miranda, and Ashley or Liara.
Yes.
No but she takes off her helmet if you do the romance scene with her
Because the people drop a couple F bombs and you can "romance" your squadmates.
No problem. Without mass, gravity has no effect anyway.
In Mass Effect 3, you can romance Kelly Chambers, but if you've already had dinner with her and she fed your fish, it indicates a previous romantic interest. However, you cannot romance both Kelly and Samantha simultaneously, as the game has specific romance paths. If you pursue Samantha's romance, it will prevent a romantic relationship with Kelly from developing further. Choose your romantic interests wisely, as they can affect your relationships and interactions throughout the game.
The mass of a solid is the amount of matter that it has that determines its heaviness without the effect of gravity. Its standard unit of measurement is kilogram.
If he died in Mass Effect 1 then he is not in Mass Effect 2. If he survived Mass Effect 1 he shows up in Mass Effect 2 but he can not be killed.
No, you have to complete the whole main story mode and depending on what level your at you'll start off with some xp in mass effec 2
No you cannot. If you're a girl character, your options are Kaiden or Liara. You can romance Garrus in the second one, though!
