How exactly did the T-1000 get through the time portal?
After all, he is not living tissue, nor is he surrounded by it like the T-800's. You can't argue that the time equipment has been updated since both Terminators in this movie still come back naked and unarmed.

John Connor: No, no, no, no. You gotta listen to the way people talk. You don't say "affirmative," or some shit like that. You say "no problemo." And if someone comes on to you with an attitude you say "eat me." And if you want to shine them on it's "hasta la vista, baby."
The Terminator: Hasta la vista, baby.
John Connor: Yeah! Or "later dickwad." And if someone gets upset you say, "chill out"! Or you can do combinations.
The Terminator: Chill out, dickwad.
John Connor: Great! See, you're getting it!
The Terminator: No problemo. 😮💨 😕 🙄
