I recently mentioned that Quake has moved a lot closer to her tv counterpart, Skye (and I didn't mention it, but Skye is also moving closer to her comics counterpart, Quake). And this month's Quake: SHIELD 50th Anniversary Special #1 (September 2015) continues that trend.
In SHIELD #7 (June 2015), we learn that Quake's mother is an Inhuman. This month, Quake meets an Inhuman named Jiaying who implies she knew Quake as a little girl.
If that name sounds familiar to you, it's because Jiaying is the name of Skye's mother (an Inhuman) in Agents of SHIELD. She first appeared in the episode "The Things We Bury" (November 2014).
