Can someone tell me what does he say, and what does it mean?

SKIP TO 2:03:53

Teşekkürler!

he said çöz şu işi.

Does it mean "fix this" or "work this out" something like that?

And can you please help with what he says at 2:01:06

After "Ömer seni çocuk mocuk yüzünden terk etmedi"

Btw (what does "mocuk" mean?)

Yes

Mocuk have no meaning when its used alone.

Also if we remove mocuk it would be correct, but there is difference and its hard to explain in english.

Another example

yaşına başına bakmak

You can see that words are similar.

yaş-baş

çocuk-mocuk
