My ideal immediately-post-reunion dynamic for Grace and Adrian is this:
Grace: It is vitally important that I get along with Adrian. This is my best friend's mate, the person he fought so hard to come home to, and the most important person in his life. Yeah it's a little awkward because they've been together way longer than I've been alive and I'm just some alien he picked up on the way and will probably forget about once he has his real family back, but I've still gotta make this work. For Rocky.
Adrian: It is vitally important that I get along with Grace. This is the person who saved our entire species and brought my mate home to me. I owe him everything for that, and he clearly means the world to Rocky. Yeah it's a little awkward because I haven't seen my mate for years and now it's like I barely know him anymore and he's closer to this weird new alien than he is to me, but I've still gotta make this work. For Rocky.
This leads to Grace and Adrien having many conversations in front of Rocky which are very polite and nice and accommodating- and excruciatingly awkward.
Rocky puts up with this for a few weeks before conspiring to lock the two of them in a room alone together, where they eventually manage to have an honest conversation, bond over their mutual love of science (and of Rocky) and become fast friends.
