Now this, would be an interesting switch, One I'd like to see in fact.
I'm really disappointed with how they've portrayed Amber this season. They've shown her become pregnant in an accidently-on-purpose type way (hello, morning after pill?), which is fine if TPTB showed her actually own the decision. Instead they have her whine about not being able to drink or smoke; not planning/thinking at all with regards to how the frick she's actually going to manage; not wanting to tell Ryan etc etc.
If she had planned/hoped to get pregnant under some misguided romantic notion of trying to hold onto Ryan (or even just the memory of Ryan) it wouldn't have been wise, but would have been understandable if she went full steam ahead with pregnancy & motherhood. Instead, we have her go through with a pregnancy that she's really not on board with. For what end?
