Hazrat Esa (Alayhis Salaam's) coming back to this world

Q: A christian asked me what do the Muslims believe about Hazrat Essa (Alayhis Salaam) when he returns to earth? She believes or has been told in the bible that Hazrat Essa (Alayhis Salaam) will return to earth get married to a beautiful lady and he will be the new ruler of this world. I replied that is incorrect. Yes, Hazrat Essa (Alayhis Salaaam), will return to this world, he will break the cross, kill the Dajjal. Please could you give me a better explanation. Though I do know as Muslim whatever we answer to these Christians they will never accept what we as Muslims know is the truth.

Doubts

Q:

Salaah: During prayer, I have a problem to recite properly and I focus on correct pronunciations. So I have to repeat again and again. Due to this my prayer goes too long. Even my four rakaats complete in 20 to 25 mins (one rakat takes 5 to 7 mins ). Zuhr takes one hour 10 mins. Please help me.

Wudu: If a person pours and splashes water on face three times and later on during salaah some doubts comes to mind weather his face was fully wet or not so what should he do? Continue to perform salaah or break the salaah and do wudhu again?
