I'm not saying Shulkie got lucky the first time, I was offering an explanation how that fight might look through Titania's lense. It's not exactly uncommon for villains to search for excuses as to why they lost before and to demand a rematch. Also as far as I know it's pretty much Titania's shtick in the comics that she comes back to challenge Shulkie all the time despite the fact that she has lost basically every encounter apart from one where she was juiced up by the Infinity Gem or what it was. So she's more or less behaving like her comic counterpart here.
I pretty much got the vibe from the first issue of Shulkie's current run where Titania confronts Jen in her human form, starts knocking her around and demands for her to turn She-Hulk. And after that happened she got her ass kicked. Same pretty much happened here.
Well she did better in my opinion. The first time was literally a one punch knockout. In this Titania was basically outskilling Shulkie, dodging and getting four or five hits in before Shulkie was able to connect once. And that punch didn't take her out, she was ready to continue but then she slipped.
