Tense problems. Can anyone help me with the following in the book Harry Potter and the Philosopher's Stone, Chapter 11: Qudditch, page 135:
(1) That's where he was going when we saw him
(2) he's after whatever it's guarding!
(3) "No - he wouldn't," she said. "I know he's not very nice, but he wouldn't try and steal something Dumbledore was keeping safe."
In the above context, can anyone tell me and explain to me:
(1) "That's" actually means That is or That was?
(2) "he's and it's " actually mean he is and it is or he was and it was?
(3) "he's" actually means he is or he was?
Thanks a lot for your help!
