They had hardly slept that night and then Max tackled her out of nowhere, so the irritation is obviously understandable.
But still, her lack of enthusiasm there disappointed me. The day prior, she's had the outburst in the car. So they must have had their making-up, Chloe apologizing and whatnot, obviously having realized how wrong she had been doing Max and how much she wanted to be with her again, probably beating herself up about it the entire time before they met up again.
So at least after the initial irritation and surprise wore off, it would have been nice if there had been a little more visible and audible appreciation of Max's affection there, instead of just going "you sound high, but thanks for the morning grope", and then "hope you weren't messing around with time".
This is especially disappointing precisely because apart from the couple of text messages, we do not get to see anything of their making-up, and because it comes right after the highly emotional and narratively significant scene in the alternate timeline.
Yes, they also wanted to contrast the conditions of the Chloes, show her typically more "pissed off" mood in the original universe... but that doesn't mean she wouldn't let show that Max hugging her and saying she's so glad she's there makes her happy.
The scene could have been more emotionally and romantically impactful altogether, but even just a little smirk, a lingering hand, a rise in voice or some other little sign of appreciation would have been nice.
There's more scenes that are narratively highly significant, and particularly romantically so, that lack some of that viscerally emotional and outright romantical impact. They are still important and nice scenes, romantical ones, but I really think the lack of a little more sappiness in some of them is a failure that perhaps having a woman on the team could have helped avoid.
