My theory:

Summer Rose, Ruby and Yang's mother, dies (RLR2). Yang takes over as Ruby's main caregiver becaue their dad comes apart in grief for a length of time. In that time, Yang swears that she'll protect her sister from ever feeling this way again (Shining Beacon, Part 2 & Gold). In the process, Yang subliminates her own grief for her mother so she can be strong for her younger sister. She does this to the point that, to outside observers, it isn't even present.

However, it is present and it leads to something of an obsession. As soon as she is able, Yang starts looking for clues as to what happened to Summer, a trail that finally leads her to rumours of their missing maternal aunt, who we see she is hunting in the Yellow Trailer.

Meanwhile, Ruby (probably much against her father's wishes) goes to the distant location where her mother died and spends some time meditating in front of Summer's memorial marker. When she leaves, she's angry in a way she's never been before. A pack of Beowolves volunteer as therapy (Red Trailer).

We know that the sisters' father is increasingly aware of his daughters' obsessive need to find out what happened to Summer and get revenge. That's why he's been at Ruby (and probably Yang too) to have more healthy relationships outside of the Hunter fraternity. You can even see their focus on Summer's legacy in Ruby's comment that their parents had taught them to help others.
