In the alternative timeline, Donna never meets Lance. And yet, when she is upset, and afraid, she asks Rose Tyler for a cup of coffee. Steam rises from her mug as they stand around the console inside the dying TARDIS, and have the most honest conversation they've had yet about the Doctor and their feelings towards him.

In the proper timeline, the person we see Donna drinking coffee with is Wilf. In moments of joy and moments of upset they bond over coffee. Before she finds the Doctor again, Donna brings Wilf a thermos to escape Sylvia's criticisms.

Wilf is the only person in Donna's life who she can be herself around, who has unconditionally cared for her, and who she takes joy in caring for back.

Even in the alternative timeline, Wilf has held onto not only the telescope but the exact same thermos Donna brings him coffee in when he's up on the hill.

For the Doctor to remember how she takes her coffee, we know they must have had moments together like this off-screen too.

So when the Doctor makes her a cup of coffee, just how she likes it, he is communicating he remembers not just the small details of her but that he remembers all these things that she associates with making someone a cup of coffee – kindness, acceptance, being noticed, caring for someone and being cared for, home, and family.

It's possible, for the Doctor, there's an apology in that cup of coffee too.

But wait, there's still more.

Did Donna spill the cup of coffee on the console on purpose?

The slight of hand was rather obvious. And it came at a time when Donna was trying to convince him not to leave her, to come back home to her, if only just for a visit.

He'd not said no, but she'd easily seen through him the first time he lied about coming inside to have dinner with her family that first Christmas, and likely saw through him again – the avoidance of eye contact, fiddling with the TARDIS, the wane "yeah, maybe."

She also rather clearly wanted to go on another trip with him (she never wanted to stop in the first place), and was only saying no because of her obligations to her family. It's possible she was buying time by spilling the cup of coffee – just one more than one last trip, without it being her "fault."

She had, after all, just dropped a cup of coffee on a computer and lost a job she'd probably hated, knowing Donna. And before things had gone really wrong, she'd definitely been enjoying herself.

It's also possible she's still quite angry with the Doctor, but unable to fully verbalise this yet.

He connects the cup of coffee to remembering every detail of her. She has not been able to remember any detail of her life with him. The last time they were standing around the console together, he took her memories against her will. He says it killed him; but she – or that version of herself, the one she actually liked – was arguably the one who was killed.

And she might be remembering Lance, another man she truly loved and trusted, and how a cup of coffee seemed like a kindness but was in fact a lie, a violation.

The Doctor quite possibly also suspects something like this is what might have happened, given his level of anger at her.

Despite the fact that this Doctor is more able to admit his feelings, we don't see what happened between them when he took her memories ever properly resolved in words.

Instead, there are a series of proxy arguments that stand in for it – Donna's anger that she gave away all her money because of him, that he sees taking the slow path, living a life day after day as such agony when he made her do it, his anger at her faith that he will know how to defeat the Toy Maker.

And their most emotional proxy argument of all – who is at fault for stranding them at the edge of the universe? Is it Donna, who spilt the cup of coffee, or the Doctor, who she couldn't stop from wandering off?

Thematically, however, there is some resolution. The Doctor lets Donna decide to regain her memories, even if it means she'll die. The Doctor knows Donna enough to save her from being left to die alone, even if it is at the very last moment. The Doctor admits he used to think he knew everything, but now he knows he doesn't.

Donna gets to tell him it's not all about him saving her, gets him to stop, finally gets him to come home with her.

And in their last scene, it's the Doctor who is having the cup of coffee.
