Plot hole: The past has changed, but Kyle Reese is evidently the same one who was sent to protect Sarah Connor. In "T1", he explains to her that the T-800 CSM-101s are new units, with real human tissue, difficult to recognize, and that he had to wait for the cyborg to approach her before he could identify it; this means that he had never seen a T-800 that looked like Arnie. In this film, however, as soon as he sees the T-800 "Pops", he shoots it and later claims to have never seen an "old" Terminator. (00:28:31 - 00:31:36)
