Like I needed more reasons to love Olli - Plus questions for the show veterans

I was watching some early clips of Olli during his first run...I have some questions about this clip

1st...could he be any more adorable?

2nd...I thought Charlie was Olli's aunt. Why doesn't she even know who he is in this clip? But in the next clip they are friends.

3rd...The place that the New Years party is at...is that an older version of No Limits? It looks different

4th...the place Charlie is at when she reads the books Olli left...is that Schneiders?

5th...Who is the Christian in these clips?

6th...No Limits and Schneiders are both bars/pubs, right? Schneider's is up scale and No Limits is more casual, right?

Olli is beyond adorable. How could any guy turn him away...he's so cute when he's working through his troubles. Christian better not hurt him!!

ummm...the karaoke scene...look familiar? I'l have to call my Brother and Sister and ask.
