Technically speaking, there were absolutely no implications that Mercury and his dad didn't get along well or even that he was violent. All he said was smelled like my dad after a long day. This has nothing to do with violence. People hear alcohol in entertainment and the first thing they think of is violence. Add the word parent  and it becomes ''domestic violence. Worst part is that he said after a long day''. He's specifically saying that his dad only gets drunk when the situation demands so. A lot of people do. Qrow does! And he's not beating his nieces or mistreating them in the slightest.

If there's any actual implication that Mercury didn't have a good parenting, it's the fact that he's apparently all on his own in the middle of a forest with what appears to be a campfire in front of him and a black eye. It looks like Mercury doesn't even have a home. Given his situation even though he mentioned that he has a father it's a good sign of bad parentingor just a tragedy since Mercury nonchalantly mentions his father without any hint of sadness, anger or post-trauma.
