ME1 version, since im currently replaying the trilogy and am at ME1 rn. ME3 bot is next (my favorite), so i'll see about figuring out scenarios for it. probably a generic one and maybe something to do with rannoch as a bonus, who knows
compared to ME2, she is inexperienced and rather excited here, and happy to be a part of the biggest adventure of her entire life.

currently three greetings, one where she is excited about the technology of the Normandy SR1, another where she is homesick, and a third that is a more generic greeting.

now, officially there is no romance option for Tali in ME1.
personally, anything is possible. in ME2 she does imply she had a crush on you in the first game aswell, so y'know, wouldnt be immoral in my mind. though she is two years younger here than in the other games, mind.

a shameful lack of ME1 Tali art, as it turns out. if anyone has a magical storage with every ME1 Tali fanart in existence, do let me know
