The Word Change Game

For this game, I will give you two words. The first word I give you must be changed into the second word, but only by one letter at a time. The objective is to accomplish this in as few words as possible, while each time the word is changed, it still must be a word.
Here is an example: Seed - Leap

1. Seed
2. Seek
3. Peek
4. Peak
5. Weak
6. Leap

Round One: Tent - Lime

 

[FIX] For the example problem, Five is Weak, Six is Leak, and Seven Is Leap.

 

Yep, that was an easy one. This one, not so much.
Round Two: Grill - Plain

 

No, you can only change them.
