Need help simulating quasi saturation for emitter follower in LTSpice

Hello all,

I am still learning about BJTs principle of operation and came by the concept of quasi saturation and hard saturation.
To better understand the concept I tried simulating emitter follower using popular transistor models.
I am not sure at what I am looking, but would appreciate if someone can explain.
I tried varying collector current of Q1 by changing R2 from 100R to 1K.
Probed collector current of the Q1 and I get kind of wobbly sine wave.

Sim file is in the attachment.
