Ибо Диана хотела бы не видеть Даниэля.
Значит, она его уже увидела.
Так как время Past Simple and Past Perfect.
Past Perfect -- действие до действия в прошедшем, то есть Диана не хотела, к примеру, вчера, не видеть Даниэля позавчера. Соответственно она его увидела, а потом уже думала себе, что совсем не хотела, что бы это произошло.
<span>When i was ten me and my best mate use to sleepover at each others houses on the weekends. It was my turn to sleepover at hers. In her room she had a bunk bed facing the window and i was sleeping on the top. We were watching tv and from her window you can see a row of houses and a row of trees. It was quite dark and for some reason i just looked out of the window and stared at the nearest tree, felt like someone was watching me. All of a sudden I saw this long black leg stick out from the tree and disappear!! I told my mate and when she looked nothing was there. It gave me chills whenever we played near them trees.</span>
