原句(中间无任何标点，我擅自分成3行来写容易看)：

Yesterday my husband removed the gate 

and Rex got so annoyed 
we have not seen him since.

原译文：昨天，我丈夫把门卸了下来，雷克斯很生气，此后我们便再也没有见到它。

疑问1：该句明显有3个主语3个谓语，但Rex和we这2个句子为何没有标点或连词？到底如何理解这种结构？

网上找了好久，搜索到3种理解方式，哪种最接近？：

1、Yesterday my husband removed the gate, Rex got so annoyed and we have not seen him since.

2、Yesterday my husband removed the gate and Rex got so annoyed, we have not seen him since.

3、Yesterday my husband removed the gate and Rex got so annoyed that we have not seen him since.

疑问2：我想确认一下：since在此是副词，意思是“此后；后来；”
