I hate when this show turns into the "Emily and Ty Show". They are both controlling and manipulative. They annoy me to no end and they just escalate each other.
Regarding Ty and Andrew, I wouldn't have said Ty "pushed" him. It looked to me like they were wrestling and it went to far. Andrew was so drunk that he probably would not have needed any help falling! There was one camera angle as Andrew started falling that showed Ty had grabbed his leg and was trying to get him back, but it was too late. However, having a hold on him like that could have significantly reduced the impact of that fall. If he had just taken a free-fall headfirst from that height I think he would have been much more seriously hurt! I'm no fan of Ty, I just thought that it was an accident rather than an aggressive attack.
