Your post reminded me: if Hawke has slept with Isabela (even if he moved on to romance someone else) she says "I've had better" in regards to Zevran, but she says "I've had worse" otherwise. I'm not sure if this means that Hawke is canonically better in bed than Zev but I thought it was sweet of her.
I never realized this, but oh no…this is a perfectly veiled compliment from Isabela.
Isabela, you say the nicest things. I suppose Hawke has to be moved above Zevran on the best lay list now.
