The transcript for this one could be just:

Alex: [stares in lesbian]


Panel 1 (Imogen sits up in bed and stretches her arms over her head. In the background, Alex stares in confusion.

Panel 2 (Imogen looks back at Alex, shy and a little sultry)
Imogen: Oh, you’re awake! Good morning!

Panel 3 (Imogen lies down beside Alex, propping her head on her hand)
Imogen: Thank you again for last night.

Panel 4 (Alex, still staring in shock, tries to speak, but her speech bubbles are empty)

Panel 5 (Extreme close-up of Imogen’s lips)
Imogen: I really, really appreciate it.
